Barbell clips, also called collars or clamps, are small fasteners that lock weight plates against the bar sleeve. They stop plates from sliding so your lifts stay balanced and safe.
This guide explains the main clip types, how to put them on correctly, and how to choose the right pair for your bar and training style.

Key Takeaways
- Match the size first: Olympic bars use a 2 inch or 50 mm sleeve and standard bars a 1 inch or 25 mm sleeve, so the collar must fit the diameter.
- Clamp collars win for most lifters: they apply fast and hold securely across general training.
- Spring clips are budget friendly: light and cheap, but they can loosen under heavy or dynamic lifts.
- Always tug test: seat plates flush, slide the collar tight, then pull to confirm nothing moves.
- Budget is wide: clips commonly run from under 8 dollars to over 150 dollars by type and material.
Types of Barbell Clips and Collars
Barbell clips come in four common styles, each trading speed against security. Picking the right one starts with knowing how they differ.
Loose plates are a genuine hazard, since drop and crush events rank among the most common mechanisms of weightlifting injury.[1]
- Spring collars: A spring loaded coil you squeeze open and release onto the sleeve. They are inexpensive, light, and fast, but offer less security and can loosen under heavy or dynamic work.
- Lock-jaw or clamp collars: A hinged body with a locking lever that snaps tight. They are fast and secure, durable, and the best all round pick for most lifting.
- Screw-lock or spin-lock collars: A threaded collar that twists down against the sleeve. They give exceptional security for threaded bars, but apply slowly and can be over tightened.
- Competition collars: Precise, heavy collars built for powerlifting and Olympic meets. They deliver the highest security and meet federation standards, but cost the most and are overkill for general fitness.
The short demo below walks through several real clip styles and how each one goes on the bar.
| Type | Best Use | Ease of Use | Security |
|---|---|---|---|
| Spring | Light to moderate loads, quick changes | High | Moderate |
| Lock-jaw clamp | General training, moderate to heavy | High | High |
| Screw or spin-lock | Threaded bars, maximum hold | Low to moderate | Very high |
| Competition | Powerlifting and Olympic meets | Moderate | Exceptional |

How to Put On and Use Barbell Clips Correctly
Loading is simple. Seat the plates, slide the collar tight, then tug test before you lift.
Good loading habits matter, since poor technique and form are leading contributors to resistance training injuries.[2]
- Check compatibility: Confirm your collars match the bar sleeve, and inspect them for cracks, bent springs, or worn levers.
- Load plates flush: Slide plates on evenly, with no gap between the first plate and the bar shoulder.
- Apply by type: Squeeze and release a spring collar, close the lever on a clamp, or twist a screw-lock until snug without forcing it.
- Tug test every set: Pull the collar and plates outward, and if anything slides, re-seat and lock again.
This beginner walkthrough shows how to load plates and use a barbell and rack from the first rep.
For the full sequence before clipping, see our guide to loading plates on a barbell.
Common Mistakes to Avoid
- Leaving a gap: Plates that are not flush to the shoulder shift mid set, so push them in before locking.
- Mismatched size: A loose collar on the wrong sleeve cannot grip, so always match the bar diameter.
- Skipping the tug test: A quick pull catches a loose collar before it fails under load.
- Over tightening screw-locks: Forcing the thread can damage the bar, so stop at firm resistance.
Collars are also part of a safe rack setup, as covered in our guide to squatting safely in a power rack.
How to Choose the Right Barbell Clips
The best clip matches your bar, your loads, and how often you change plates. Weigh a few factors before you buy.
Done with sound setup, traditional strength training with free weights ranks among the safest resistance training methods.[3]
- Sleeve diameter: Use Olympic collars for a 2 inch sleeve and standard collars for a 1 inch sleeve.
- Material: Plastic and nylon are cheap and light, while aluminum and steel last longer under repeated use.
- Training style: Powerlifting favors maximum hold, general fitness suits clamp or spring, and frequent changes reward quick release.
- Budget and durability: One buying guide lists prices from under 8 dollars to over 150 dollars, with higher quality lasting longer.
- Approximate weight: One guide lists about a quarter pound for spring, half a pound for clamp, one pound for aluminum, and 5.5 pounds each for competition collars.

When You Can Skip Clips
- Solo max bench: One guide notes that benching alone at maximum effort is the rare case where some lifters skip collars, so they can tip the bar and dump plates to escape a failed rep.
- Everything else: For squats, deadlifts, presses, and Olympic lifts, keep collars on, since a tilting bar can throw loose plates.

FAQs About Barbell Clips
What are barbell clips used for?
Barbell clips lock weight plates against the bar sleeve so they cannot slide during a lift. They keep the load balanced on both sides, protect your feet and joints from shifting plates, and let you focus on the movement instead of the bar.
What is the difference between barbell clips and collars?
None really. The terms barbell clips, collars, and clamps describe the same accessory that secures plates on the bar sleeve. Some lifters reserve collar for heavier locking styles and clip for light spring types, but the words are used interchangeably in most gyms today.
Which barbell clips are best for beginners?
Lock-jaw clamp collars suit most beginners best. They snap on fast, hold securely for general training, and need no real grip strength. Spring collars are a cheaper starting point and often come bundled with a bar, though they loosen sooner under heavier or faster lifts.
How do I know if a collar fits my barbell?
Match the collar to your bar sleeve diameter. Most Olympic bars use a 2 inch or 50 mm sleeve, while standard bars use a 1 inch or 25 mm sleeve. Check your bar specification first, then buy collars labeled for that size to avoid a loose fit.
Are spring collars strong enough for heavy lifting?
Not always. Spring collars are inexpensive and quick, but they can loosen during heavy or dynamic lifts when plates shift. For pressing, squatting, or deadlifting near your limit, a clamp or screw style collar gives a firmer, more reliable hold and better peace of mind.
How tight should a barbell collar be?
Tight enough that nothing moves. Push the plates flush against the bar shoulder, slide the collar snug to the outer plate, then lock it. Give the collar and plates a firm tug, and if anything slides, re-seat and tighten again before you start your set.
Do I need collars for every exercise?
Almost always yes. Collars are recommended for most working sets, especially presses, squats, deadlifts, and Olympic lifts where a tilting bar can dump plates. The main exception is benching solo at maximum effort, where some lifters skip collars so they can tip and escape a failed rep.
How much do barbell collars weigh?
It varies by type. One buying guide lists roughly a quarter pound for spring collars, about half a pound for clamp collars, near one pound for aluminum models, and about 5.5 pounds each for Olympic competition collars. Lighter clips suit general training, while competition collars meet strict meet standards.
Can I use Olympic collars on a standard barbell?
No. Olympic collars are sized for a 2 inch sleeve and will sit loose on a 1 inch standard bar, so they cannot grip safely. Use collars made for your bar diameter. Spin lock collars are the common choice for threaded standard bars.
How much should I spend on barbell clips?
It depends on use. Prices commonly range from under 8 dollars for basic spring clips to over 150 dollars for premium or competition collars. For most home and gym lifters, a mid priced clamp pair offers the best balance of speed, security, and durability.
Conclusion
The right barbell clip is the cheapest safety upgrade in your gym. Match it to your sleeve size, then pick a style that fits how you train.
For everyday lifting, fast and secure clamp collars are hard to beat, while spring clips work for light sessions and competition collars suit the platform. Lock in your plates once, and train with confidence every set.
