Proloc™ Blocker


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 Effective and efficient! I bought this after buying my own barbell and I am so happy I did. It is extremely easy to use and prevents others from using my bar. I would highly recommend this device to protect your bar if it’s kept in a gym where others might have access to it.

Rated 5 out of 5 by from Works great Worth the money if you want to use your own barbell at the gym. Better than lugging it around in the truck and possibly damaging it.

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.

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 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 Does the job and does the job well. Does exactly what it’s supposed to do. Simple to use and prevents people taking your powerbar and doing rack pulls.
