As someone who frequents the gym and has lifted heavy weights for years, I can attest that finding the right collars for my barbell has been a challenge. My gym does not have flush callers, only spring-loaded callers, and the movement of the "slop" on the plates can be very disorienting, especially when attempting to squat close to 600 pounds. This is where Lock-Jaw HEX 50mm has been an absolute game-changer for me. The fact that these collars are flush helps to solve the disorientation problem that I have faced in the past. The movement of the barbell feels much more stable and secure with these collars, which has allowed me to focus on my form and technique during my lifts. In the past, I have purchased other collars that have a rubber gasket on the inside. While they were affordable, over time, especially when leaving them in a cold car overnight, the gasket began to break down, making it increasingly difficult to get the collar on the barbell. This is not an issue with the Lock-Jaw HEX 50mm collars, as they do not have a rubber insert. They are well worth the additional price, as I have a feeling that these will last for an extremely long time and they won't have to be replaced every few years like the rubber gasket-style collars. Overall, I would highly recommend Lock-Jaw HEX 50mm collars to anyone who is looking for an excellent product that is both reliable and easy to use. These collars are flush, which provides excellent stability and support during lifts, and they are made with high-quality materials that are built to last. So go ahead, invest in a pair of these collars - your lifts will thank Review: Really great and works well - So far I am really liking these collars. They do not move when on the bar. It can be a little hard to get them clamped on because they are tight but that’s what keeps them from moving. The only thing to improve them would be to be magnetic. Would definitely buy these again. ## Features - NO MORE SLIDING PLATES OR RATTLES – Tired of loose weight clamps ruining your sets?
