Lock-Jaw Barbell Collars Sport Olympic - Quick Release Clamp (Yellow)

I am a professional barbell coach. I teach the main lifts- very similar to Starting Strength, and a bit of a mix of crossfit style programming for conditioning when appropriate.I say this to paint the picture that I have used many kinds of collars in applications where I might be pulling a 1RM or a heavy set of 5, or I might be doing a WOD with 30 cleans at 60kg.These collars hold as well as collars that cost 2 times as much, and I have no worries about them being damaged because they are made from durable plastic instead of aluminum.In my opinion, these collars are the BEST value collars. You might but cheaper, but over time you will replace them and what you buy will not hold as well as these. To get comparable ones, you would have to spend 2 times as much, and be concerned that the aluminum those collars would be made from might be mishandled and get deformed.That is about all I can say. I am very glad Lockjaw is making these and I plan to buy more of these as my equipment needs grow.
