Lock-Jaw PRO Barbell Collars - for 2" bars

A large lever and spring-loaded snap latch let you clamp the collar onto the bar with one hand — no twisting or threading required.

The PRO collar uses a cam-lever design: you position the collar on the bar sleeve, press the lever down, and the spring-loaded snap latch locks it in place. Releasing is just as fast — flip the lever and slide the collar off. This is faster than a threaded spin-lock collar and doesn't loosen from vibration the way some clip-style collars can during heavy training.

More than a standard spring collar — the PRO is Lock-Jaw's original design built specifically to out-hold basic spring-clip collars under heavy loading.

Standard spring collars (the classic coiled-wire clip) can slip or loosen as plates shift during heavy sets. The PRO collar's cam-lever mechanism applies consistent clamping pressure around the full bar sleeve, keeping plates locked through squats, deadlifts, and Olympic lifts. It's rated for commercial gym use, where collars get thousands of on/off cycles.

A durable resin frame with elastomer pads that grip the bar sleeve without scratching the finish.

The PRO collar's resin frame houses the lever mechanism, while elastomer (rubber) contact pads make direct contact with the bar sleeve. This combination protects your bar's knurling and finish from the metal-on-metal wear that some all-metal collars can cause over time, while still providing a firm, non-slip grip.

Fits standard 2" Olympic barbell sleeves. Sold as a pair, and available in 5 color options.

The PRO collar is sized for the 2" (50mm) sleeve diameter used on virtually all Olympic barbells. It's not adjustable for other bar sizes — if you're running 1" bars or 1.9" specialty bars, Lock-Jaw makes dedicated collars for those (the ONE and PRO AXLE). Each order includes one pair (2 collars), enough for one barbell.

Yes — every Lock-Jaw collar carries a 1-year manufacturer warranty against defects in material or workmanship.

As an authorized Lock-Jaw dealer, Blue Sky Fitness Supply handles warranty claims on your behalf — you're not chasing the manufacturer directly. The 1-year term covers manufacturing defects in the locking mechanism, frame, and finish under normal training use. Full coverage and exclusion details are on our warranty information page under the Lock-Jaw section.

Orders process within 3 business days and typically arrive within 3-5 business days of shipment.

Lock-Jaw collars are small parcel items, so there's no freight or liftgate to schedule — they ship the same way as any small package. For facility buyers ordering collars alongside racks, bars, or plates, we can bundle the order onto one purchase order so there's a single document to process. Full shipping details, including current rates, are on our shipping policy page under the Lock-Jaw section.

Contact us within 30 days of placing your order to request a return. Requests made outside that window may not be approved.

Blue Sky Fitness Supply requests that customers who wish to return purchased goods for any reason reach out within 30 days of placing their order. This gives you a full month to try the collars in your training before the return window closes. Full return and refund policy details are on our return and refund policy page under the Lock-Jaw section.

Lock-Jaw collars are designed and manufactured in the USA by Avus Design, a California-based company focused on barbell collar design and clamping technology.

Lock-Jaw's collars are used in universities, professional sports weight rooms, gyms, and high schools — environments that demand reliability under constant, heavy daily use. The Solid Metal collar line was developed in conjunction with powerlifting strongman Leroy "The Machine" Walker, reflecting the brand's focus on maximum clamping force for serious lifters. As an authorized Blue Sky dealer product, every Lock-Jaw collar you buy from us is backed by the manufacturer's 1-year warranty.
