How to Choose Barbell Collars

Match your bar size

Olympic bars use 2 inch (50 mm) sleeves, so look for collars made for 2 inch bars. Standard 1 inch bars need a different size.

Pick the lock type

Quick-release lever collars are the fastest to use. Spring clips are cheapest, and magnetic or screw-on styles suit specific setups.

Check the grip

A good collar grips the sleeve firmly without slipping. Read reviews for sliding under load.

Think about speed

If you change plates often, a lever collar saves time between sets.

Look at the build

Composite, nylon and steel collars all work. Check that the lever and hinge feel solid.

Buy a pair

Collars are almost always sold in pairs, and a single pair covers one barbell.
