The Proloc 1 collars can be used on Olympic barbells and specialty bars. The super-strong Nylon build feels sturdy in hand, and the easy-to-tighten screw attachment makes for quick work when adding or removing the collar. The collars magnets also make it easy to attach the collars to your rack, storage unit, or any other piece of metal in your gym.


  • Strong Nylon Design.
  • Magnetically attaches to any metal in your gym.
  • Very strong grip.
  • Easy one-handed tightening screw adjustments.
  • Fits Olympic and Speciality Bars.



  • The screw is prone to stripping. 

Proloc 1 Collars are made in the USA and built with durable nylon plastic. The collars can be used on a standard Olympic bar, such as the Rogue Ohio Bar, but also on specialty bars with a non-standard sleeve size, for example, the EliteFTS SS Yoke bar and the Bells of Steel Arch Nemesis Swiss Bar.

These collars are currently a mainstay in my gym, mainly for use with my Yoke bar and several specialty bars that feature steel tubing in place of standard 2″ sleeves.

The Proloc 1 collars offer an easy-to-apply slide design that can be tightened using the attached knob at the top of each collar.

I was skeptical of using collars that didn’t feature a snap-closed design or a spring. My worries were immediately alleviated once I tightened down the knob, and my bumper plates remained firmly in place.

The adjustable design of these collars means they fit on sleeves ranging from 1.937 inches to 2.007 inches.

Dropping weights ranging from 100 to 400 pounds has caused zero damage to the collars. I perform CrossFit movements that constantly lead to drops from above my head, and I’ve bailed quite a few times on squats and deadlifts that have left my weights bouncing off my rubber gym flooring.

The second you put these collars in your hand you’ll be convinced that they are a solidly built option, and that’s saying a lot considering the various premium quality products offered throughout the powerlifting industry.

Proloc 1 Collar – Magnetic Storage

One of my favorite features for these collars is the ability to attach them directly to my Rogue Mass Storage unit thanks to built-in magnets on the back of each collar.

Here’s how that looks:

The Proloc 1 collars admittedly don’t have the strongest magnetics, which means they sometimes slightly shift during use. The shift has never caused any issues, but it’s my one piece of truly negative feedback, given how much I attempt to protect my expensive gym equipment from accidental scratching.

Still, the magnet is great for quickly moving my collars out of the way without taking up additional space on my storage racks.

Proloc 1 collars feature a 2-year warranty against material defects and workmanship. Based on my testing, you won’t need the warranty, but at the price point, it’s a nice option to have available.

2023 Update: I first posted this review on August 15, 2020. It’s now February 21, 2023, and here’s how the collars look after multiple years of regular use.

At a cost below $60, the Proloc 1 collars are the only option you need in a gym. They stand up to the test of time, they look great, and they fit on non-standard and standard bars. Their construction is also top-notch.
