ironcompany Lock-Jaw 1 Inch Barbell Collar Pair Black

Works great. Very secure

Perfect fit. Easy install.

Okay these get a 5 star only because I was able to use them on my dumbbells, and not my barbell. You see these are supposed to fit a thicker size 1 inch bar. I didn’t know that there were thicker and thinner bar sizes. It doesn’t work on your thinner style 1 inch bar, but great on the thicker. If you think yours make be one of two lock jaw does sell the smaller bar ones too! I got these for dumbbells and they are good quality and built nice wish the advertising was a bit for clear but it’s okay I caught it.

Barbell lock fits perfectly on my 1 inch equipment

Strong and secure grip. Perfect for my dumbbell handles.

The product seems to be well made, and of adequate strength for the application (which worried me a bit because it's mostly plastic rather than steel). It would probably work just great on a solid 1" metal barbell. My bar has long threaded ends, onto which a nut is spun to hold the weights in place. This method is very secure, but can be time-consuming to spin the nut over nearly a foot of bar to add or remove a weight - times two, for each end. So this clamp seemed like the perfect solution. Unfortunately, even though the outer diameter of the bar ("major diameter of the thread") is a standard one inch, the clamps would not lock securely onto the shaft. They weren't loose enough that the weights would uncontrollably slide off, but they weren't held snugly against the stop collars either. I've temporarily allayed the problem by adding an inner layer of thick tape to the rubber clamping surface, but I'll be replacing these with the traditional (harder to use) metal heliacal spring type. To be fair, the description for these clamps makes no mention of threaded bars, although other brands of the same type of item do. Again, these may work just fine on a solid bar, but didn't meet my needs.

Easy to use. Great grip on the bar.

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. GREAT PRODUCT, TERRIBLE PRODUCT DESCRIPTION
