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.
