Proloc™ Blocker

$54.00 CAD

Lock your bar down

The Proloc™ Blocker is great if you have to store gear in a public gym.  The Blocker locks one end of the bar which renders the bar useless.  Use a chain to secure your bar to a fixed object.  You can also use it on weight trees if you don't want anyone using your plates.  


  • Blocker is sold individually
  • Comes with Allen key
  • Fits all standard and specialty bars with standard size Oly sleeve

Lock is not included.

Rated 5 out of 5 by from Keeps my bar from being abused I keep my power bar at the local (commercial) gym. I was storing it in an office there and one day came to train only to discover my bar was being used by a bunch of jabronies deadlifting and dropping the bar at waist height. Lucky the bar wasn't damaged. Since then I've purchased a blocker and my bar hasn't been touched since. I put the blocker at the end of the bar to render it useless. I will probably buy another one for my log bar.

Rated 5 out of 5 by from Easy Protection I bought this for my texas power bar which I use in my high school weight room. It does its job and keeps freshman paws off my nice bar. It also works with a basic master lock which is convenient.

Rated 5 out of 5 by from Simple to use I keep 4 personal bars at my gym. I link a chain to each of the ptoloc blockers while in the bar tree. it’s very easy to manage.

Rated 5 out of 5 by from Great product This lock is perfect for the gym where I just moved. I had my deadlift bar in the gym for a week before the lock came in and I came in the gym on day to see someone benching with it. Now I don’t have to worry about anyone ruining my deadlift bar. Will definitely be purchasing some more for specialty bars I have

Rated 4 out of 5 by from Does everything you need it to I bought this to go with my new Ohio power bar as I keep it in the back room of a globo-gym. It works well and no one has used my bar without me there to allow it. I am very happy with the purchase, as well as the quality & function of the product. I only wish they made a steel version for a bit of added security, between a chain and quality padlock, the plastic body of the Proloc is the weakest link security wise.

Rated 5 out of 5 by from Great for commercial gym I bought this last month because I bought my own barbell to keep at the gym I attend. I keep it in a cupboard but there's another barbell in there too so I didn't want to risk them getting mixed up, or just getting used by other people if I'm not there. This lock is just the thing. It stands out from the other barbell and ensures that no one is using it without my permission.
