Overview
Rogue Proloc™ Collars are among the most versatile and reliable weightlifting collars on the market. Manufactured in the USA from high-durability 1.75" thick nylon, these collars feature a universal design that fits a broad range of sleeve diameters. Unlike standard collars that only work on Olympic bars, Proloc collars are engineered to secure plates on everything from standard barbells to specialized strongman equipment like axles and logs.

Compatibility Guide
Because of their wide adjustment range, these are considered legitimate "universal" collars for a training facility. They are compatible with:

Specialty Bars: Rogue Axle, Camber Bar, Safety Squat Bar, Swiss Bar
Strongman Equipment: Log Bars, Farmers Walk Handles
Other: Junior Bars and most loadable dumbbells.
Performance Benefits
Strongman Versatility: Solves the problem of standard collars sliding on 1.9" diameter specialty pipes. The Proloc mechanism can be tightened down to "bite" onto smaller sleeves where spring clips fail.
Equipment Protection: The internal mechanism utilizes a roller rather than a pin, allowing it to grip tight without marring or putting "dents" in high-end barbell sleeves.
Reliable Security: Once tightened, these collars offer a vise-like hold that prevents plate movement even during heavy deadlifts or aggressive, high-impact drops.
Ease of Use: The large top knob is ergonomic and can be operated with one hand, facilitating fast weight changes during multi-athlete training sessions.
Maintenance and Care
Thread Care: Periodically check the adjustment knob threads for debris or metal shavings. Maintaining clean threads ensures smooth operation and prevents cross-threading.
Warranty Note: The 2-year warranty does not cover damage caused by the disassembly of the threaded knob or incorrect replacement leading to cross-threading.
Cleaning: Wipe the nylon body with a damp cloth. Avoid harsh chemicals that could degrade the plastic or the internal roller mechanism.
Frequently Asked Questions
Q: Will these fit my standard 1-inch barbell? A: No. These are designed for bars with a nominal 2-inch (50mm) sleeve diameter, specifically ranging from 1.937" to 2.007".
Q: Do I need tools to tighten them? A: No. The Proloc design is intended for hand-tightening only. Do not use wrenches or pliers on the knob, as this can damage the internal threads.
Q: Are they as fast as spring clips? A: They are slightly slower than a spring clip but faster than a screw-lock collar, while providing security that far exceeds a standard spring clip.
