2x2 smith machine attachments are the fastest way to add training variety to a home gym, because the 2x2 inch uprights on Smith machines like the RitFit M1 PRO also accept many rack attachments. This guide ranks the five best 2x2 attachments, from a hack squat and a 264 lb weight stack to rotary cable arms and lever arms.
Every recommendation is a real RitFit product with listing verified mounting specs. Compatibility still depends on upright size, hole diameter, and hole spacing, so check your machine manual and the product page before buying.
Quick Answer: The five best 2x2 smith machine attachments for expanding your home gym are a hack squat for leg volume, a 264 lb weight stack for faster cable work, aluminum pulleys for smooth lat pulldowns, rotary cable arms for any cable angle, and lever arms for guided pressing. Verify upright size, hole diameter, and hole spacing before buying.
Key Takeaways
- Best hack squat: Bolts onto 2x2, 2x3, and 3x3 uprights with a 1 inch pin and adds quad focused squat and calf raise variety inside your existing footprint.
- Best weight stack: A 264 lb selectorized stack, built for one Smith machine frame only, that swaps pin changes for plate loading on every cable set.
- Best cable upgrade: 3.54 inch aluminum pulleys replace stock plastic wheels for smoother, quieter lat pulldowns and rows, starting at $32.99 for a 2 pack.
- Best rotary cable arms: 9 horizontal positions and 6 vertical angles turn one upright into a multi angle cable station rated for a 230 lb vertical static load.
- Best lever arms: A 9 position swivel and a 260 lb static load rating bring guided pressing and rowing to 2x2 uprights behind dual locking pins.
1. Best Hack Squat 2x2 Attachment: RitFit AT02A
The RitFit AT02A Hack Squat Attachment turns 2x2 uprights into a guided lower body station for hack squats, reverse hack squats, and standing calf raises. It mounts to 2x2, 2x3, and 3x3 uprights with a 25.4 mm pin that fits rack holes over 26 mm, which is the 1 inch hole standard.
A slotted mounting design fits hole spacing from 3.54 to 4.33 inches, and 7 height positions in 30 mm increments dial in your start and end range of motion. The attachment loads with standard Olympic plates, so you use the weight you already own.
- Leg variety: Adds hack squats, reverse hack squats, and calf raises without a standalone machine.
- Space efficient: Trains inside the footprint of the machine you already own.
- Warranty: Backed by a 1 year warranty covering defects in materials and workmanship.
Varied loading techniques are linked to muscle growth in a systematic review of advanced resistance training methods, and a dedicated hack squat slot is a practical way to add quad focused variety to leg day.[1]
Reviews currently average 3.1 out of 5 across 25 ratings, and the recurring theme is fit, so measure your upright holes before ordering. Buyers whose racks match the 1 inch hole spec report a serious quad burn and compact, convenient storage.
At $259.99 list price, it costs far less than a standalone hack squat machine. Check the product page for exact compatibility before you order, and give your rack a once over for hole diameter and spacing.
"I absolutely love the flexibility of being able to do many different things with one attachment. It is sturdy and stores really nicely too."
Charla D. Verified Buyer, RitFit AT02A Hack Squat Rack Attachment for 2"X2", 2"X3", 3"X3" Rack
2. Best Weight Stack: RitFit WSM1
The RitFit WSM1 Weight Stack Set adds a 264 lb selectorized stack to the M1 PRO Smith Machine, so cable resistance changes with a pin instead of a plate. The listing calls it a 30 minute install with pre assembled plates and clear instructions.
Each side stacks 12 plates at 11 lbs, and the included weight carriage holds up to 308 lbs of extra plates per side for a combined 440 lb capacity. A 5 degree incline keeps plates seated, and the anti slip locking pin holds your selection through fast changes.
- Fast load changes: Pin selection supports dropsets and supersets with no plate handling.
- Capacity: 264 lb stack plus carriage support up to 440 lbs combined.
- Warranty: Backed by a 1 year warranty covering materials and workmanship.
Machine based strength training produces strength and hypertrophy outcomes comparable to free weight training, per a systematic review and meta analysis, so a selectorized stack does not trade results for convenience.[2]
Verified buyers rate it 4.9 out of 5 across 62 reviews and consistently call out faster, smoother cable workouts. At $999.99 it is the largest line item on this list, priced against years of never loading a plate for a cable set.
The WSM1 is designed exclusively for the M1 PRO, so confirm you own that frame before ordering. If you are still choosing a machine, the M3 Power Rack Cable Crossover Smith Machine bundles a cable system into an all in one setup.
"Weight stack is phenomenal. Great addition to the M1 pro machine. Makes cable workouts so much easier. Workouts are more efficient. Really solid!"

3. Best Cable Upgrade for Lat Pulldowns: RitFit Aluminum Pulley Set
The RitFit Rack Attachment Aluminum Pulley Set upgrades the cable path your lat pulldowns and rows travel on, swapping stock plastic wheels for 3.54 inch aluminum pulleys. It works with cable attachments that use a standard cable and hardware matched to its 0.39 inch bore.
High density EMG research shows front lat pulldowns strongly excite the lats and pecs when the cable path is set up correctly, and smooth pulleys are what keep that path consistent rep after rep.[3]
- Smooth pull: An aluminum wheel and 0.98 inch width track the cable with less friction and noise.
- Options: 2 pack at $32.99, 6 pack at $59.99 in black, red, blue, or green, and 10 pack at $75.99.
- Warranty: Backed by a 1 year warranty covering defects and issues.
Verified buyers rate the set 4.8 out of 5 across 19 reviews, and the recurring report is smoother travel with less drag than the plastic pulleys it replaces. One buyer described lat pulldowns, triceps pushes, and cable rows as smooth and quiet after a 20 minute, one person swap.
Confirm the bore size against your hardware before ordering, and inspect cables, bolts, and attachment points regularly as the listing advises. Match your set size to the number of wheels on your cable system before you buy.
"The custom red pulleys make the M1 2.0 red/black even more customized. They are aluminum and very smooth. The installation was super quick and simple. I totally recommend this to make your home gym more custom."
Richard S. Verified Buyer, RitFit Rack Attachment Aluminum Pulley Set
4. Best Rotary Cable Arms: RitFit TAM1 Tornado Arm
The RitFit TAM1 Tornado Arm mounts only on the M1 PRO Smith Machine and turns one upright into a multi angle cable station. Its 9 horizontal positions and 6 vertical angles cover chest flyes, face pulls, presses, rows, curls, and lateral raises without extra cable stations.
The working height runs from 7.48 to 82.87 inches, with usable cable height from 9.45 to 79.53 inches. Built from Q235 steel with thick reinforcement plates, it carries a 230 lb vertical static load and a 150 lb angled static load.
- Angle range: Set the cable low, mid, or high and match resistance to your natural movement path.
- Smooth travel: An 8 bearing large roller system keeps the carriage steady under load.
- Capacity: Rated for 230 lb vertical and 150 lb angled static loads.
Verified buyers rate it 4.7 out of 5 across 34 reviews and highlight the extra range of motion on flye variations. At $219.99 for the arm without an extra cable, it undercuts most second cable stations by a wide margin.
The listing designs it only for the M1 PRO, so confirm that match before ordering. Compare the bundle options on the product page if you also need cable, since versions with cable run $249.99.
"Love these Tornado Arms! Very smooth and opens up a variety of new exercises."
Lonnie S. Verified Buyer, RitFit TAM1 Tornado Arm Attachment (Only for M1 PRO)
5. Best Lever Arms: RitFit LAM1 Adjustable Lever Arm
The RitFit LAM1 Adjustable Lever Arm turns the M1 PRO into a guided pressing and rowing station with a fixed movement path. Dual locking pins and a heavy duty anti drop strap hold the arm in place, so the path stays stable under load.
A 9 position swivel and a 5 position handle spaced 15 degrees apart let you tune the start and end of each rep, and moving the weight horn along the arm changes the effective load without extra plates. Each detachable horn holds up to 130 lbs of standard 2 inch Olympic plates, and the rated static load is 260 lbs.
- Guided path: Handles chest presses, rows, shoulder presses, and squats from one pair.
- Steel build: Q235 steel with 2x2 inch tubing and 31.5 inch long arms.
- Quiet details: Triple knurling, felt lining, and protective pads reduce rattle and rack wear.
Research comparing machine and free weight squats in recreationally active women reported comparable gains in lower body power, speed, and change of direction from both styles during an initial training phase.[4]
Verified buyers rate it 4.8 out of 5 across 11 reviews and call the adjustable handle a genuine differentiator. At $239.99, it mounts only on 2x2 uprights, which is exactly the spec this guide covers.
"Definitely love the ritfit lever arm, especially the adjustable handle, which is a unique design I rarely find on other brand and really make the difference. Adding a lot of variety to my workout routine."
Xiangbo P. Verified Buyer, RitFit LAM1 Adjustable Lever Arm Attachment (Only for M1 PRO)
How do 2x2 Smith Machine attachments expand your home gym?
2x2 Smith Machine attachments expand a home gym by adding standalone machine functions to a frame you already own, so you train more movement patterns without more floor space. A hack squat, a weight stack, smooth pulleys, rotary cable arms, and lever arms together cover leg, back, chest, and arm work in one footprint.
The right first attachment is the one that closes your biggest training gap. For lower body, the RitFit AT03 Belt Squat Attachment loads the legs without spinal compression on the same 2x2, 2x3, and 3x3 adapter, while the RitFit LEM2 Leg Extension Attachment is built only for the M2, which uses RitFit's larger 60 x 60 mm uprights.
Build the rest of the setup in stages through the Rack Attachments collection, starting with the attachment that answers your weakest lift.
"You really don't have a gym if you don't have a power rack in my opinion. Good old trusty power rack, it's just really great to have this much variation in your home gym setup."
Dr. Mike Israetel, PhD in Sport Physiology, Co-founder, Renaissance Periodization
FAQs About 2x2 Smith Machine Attachments
What attachments fit a 2x2 smith machine?
Attachments that match your machine upright size, hole diameter, hole spacing, and mounting style are the right fit. A 2x2 label alone is not enough, because rack width, pin length, hardware design, and product series compatibility can still differ between brands and models.
Are 2x2 smith machine attachments universal?
No. 2x2 smith machine attachments are not always universal, even when the upright size looks the same. You should confirm the product page, rack manual, hole diameter, hole spacing, and hardware requirements before buying, especially for lever arms, cable arms, seats, and large leg attachments.
Which 2x2 smith machine attachment should I buy first?
Buy the attachment that solves your biggest training gap first. Choose a hack squat attachment for leg variety, a weight stack for faster cable changes, a lat pulldown for back training, rotary cable arms for cable angles, or lever arms for guided pressing.
Can a rack attachment replace a standalone machine?
Yes. A rack attachment can replace some standalone machine functions when it is compatible, stable, and suited to your training goal. Hack squat attachments, lat pulldowns, lever arms, and cable arms can save floor space, but they may not feel identical to commercial machines.
Is a hack squat attachment worth it for a home gym?
Yes. A hack squat attachment is worth it if you want more lower body training without adding a full standalone leg machine. It is most useful for quad focused squats, calf raises, and lifters who want guided leg work from a rack based setup.
Do lever arms work like a chest press machine?
Yes. Lever arms can mimic some chest press machine patterns when mounted correctly on a compatible rack. The feel depends on arm length, handle position, loading angle, and bench setup, so they should be viewed as a versatile rack attachment rather than an exact machine duplicate.
How much space do smith machine attachments need?
Smith machine attachments need enough space for mounting, loading, movement, and safe entry or exit. Small cable handles need little room, while hack squat attachments and lever arms may require several feet of open space in front of or behind the rack.
What should I check before buying a lat pulldown attachment?
Check rack compatibility, cable height, leg holder position, seat setup, pulley path, and handle clearance before buying a lat pulldown attachment. You should also confirm whether the attachment is designed for your exact rack series, because many lat pulldown parts are not universal.
Conclusion
The five best 2x2 smith machine attachments that expand your home gym are the AT02A hack squat for leg volume, the WSM1 weight stack for cable speed, the aluminum pulley set for smooth lat pulldowns, the TAM1 Tornado Arm for cable angles, and the LAM1 lever arms for guided pressing. Each one adds machine function to uprights you already own.
Pick the attachment that closes your biggest training gap first, and verify upright size and hole spacing before ordering. If you are new to budget home gym building, start with the RitFit discount guide.
Disclaimer
Always read the product manual and confirm compatibility with your specific 2x2 machine before installing any attachment. Consult a qualified fitness professional or medical provider if you are unsure about exercise form or training intensity.
