ProlocBlocker Collar - Lock Your bar and Weight Plates - Fits Most Bars and All Olympic Bars - Made in USA

I have my own bar at my gym so I bought this to keep people from using it and ruining it like they do the gym's bars. This with a nice bright brass lock has worked well to keep people from using it. I also leave my nice collars on the inside of the lock so I don't have to carry them in my gym bag. It's certainly only keeping honest people honest but that's all I really needed. Just something to let others know it's someone's personal bar. At almost $400 I didn't want everyone using it. This has been a good buy for my need. I did also but a steel cable in case I need to anchor it but so far I haven't had any issues that I think I need to. The lock I got fits easy with plenty of room for my cable or a chain.

I’ve been using this barbell collar lock for over a year now, and I finally decided it deserves a review. It does exactly what I need it to do: keeps others from using my barbell at the gym.Yes, someone mentioned in another review that it can technically be removed with any Allen wrench, and that’s true. But honestly, if someone is bringing tools just to remove your lock, they’re basically stealing your barbell—nothing can stop that kind of behavior.Bottom line: Obviously, use at your own risk, but my gym has a good community, and this lock does the job for me.

It does what it need to do

Works really well

Product works as described. We use it on our log press to keep it safe while stored at the gym. Works perfectly and was delivered in a timely fashion.

Does exactly what it says.

This is a complete waste of money. It arrived missing the set screw that actually locks the collar to the bar, kind of the most important piece. Made of plastic. This collar is very easy to break into and unlock. Very disappointed with this product.
