Review: Better than regular spring loaded locks! - Work excellent for the 1 inch cap ez curl bar I got. Another reviewer told me the spring loaded grips that the bar comes with stink so I bought another spring type grip one then saw these and they are much better than the other two conventional ones. Pros Faster to change weights Faster to lock and unlock compared to conventional spring ones More stable and weights don’t jiggle around I am doing the BodyBeast program where I am constantly changing the weights and a big part of my near hour almost daily workout is changing the weights so anytime or something that makes my workout easier I am a big fan of! I do recommend these collar locks. Hope this helps you! Please let me know if you found my review helpful! Have a great day!! Review: Very secure - Works great.

I think, as mentioned here, Olympic bars have a thicker diameter bar. **Q: Is this sold individually or as a pair?** A: They are sold as a pair. **Q: I have 28mm (not 1 inch) smooth bars. Will these fit?** A: On a 1 1/16" bar they are a tight fit. Since a 28 mm bar is equivalent to about 1 7/64" I doubt that they would fit. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Better than regular spring loaded locks! *by R***5 on May 7, 2020* Work excellent for the 1 inch cap ez curl bar I got.

Very secure ### ⭐⭐⭐⭐⭐ Great item, but very confusing description *by B***R on March 13, 2012* I couldn't tell if $19.99 was for a single collar or a pair of collars from the description of this item. The photo shows 2, but the product description's wording sounds like you just get one. Amazon customer service also said that this is for just one collar when I inquired. I had a hard time believing it, why would they sell just one collar? You would need 2 for practically any use. Well, they were wrong. This is a pair of collars, you get a package of 2 for the money. And they are STANDARD sized (1 inch) collars, not OLYMPIC (2 inch) like it states in the product description. LockJaw needs to fire whoever wrote the description. But the collars are WONDERFUL. They fit both smooth and screw on bars very securely. I even have 50 lb plates and use heavy amounts when I bench or squat, no problem. These are lightweight and very easy to use. They go on and slide off with ease, and lock tight. I had previously purchased the spring clips which are a total waste. They were way too tight and very difficult to get on and off the bar. I felt like I was going to eventually scratch the chrome coating off the bar. And the spring clips do not work at all on the screw-type weight bars. LockJaw has made an awesome product here. And $19.99 with free shipping is the best price you will find anywhere. That's why I gambled and bought them, hoping amazon customer service was wrong about how many would be shipped.
