Proloc™ 2 Chain Collars

Name: Proloc™ 2 Chain Collars
Brand: Rogue Fitness
Rating: 3.47 (5 reviews)

Rogue’s Proloc™ 2 Chain Collars are a USA-made nylon barbell collar built specifically for chain and band training. Each collar in the pair ships with a 0.625” carabiner, letting chains or bands clip directly onto the collar instead of being looped around the bar sleeve or a spring collar. They fit standard 1.937”–2.007” Olympic bar sleeves, use a simple hand-adjustable compression mechanism to lock down, and are rated by the manufacturer to hold up to 675 lbs of chain per collar. Rogue backs them with a 2-year warranty.

Independent coverage is limited to two YouTube reviews rather than a major expert-review outlet, but both are net-positive. A long-term review after more than a year of regular use calls them “my most used collars” with almost no wear, while a 3-way premium-collar comparison praises the chain/band versatility (one reviewer even used the carabiner for a landmine-row handle) but flags the thick nylon body as a mild durability question mark and notes they lack the magnetic rack-storage some competing collars offer. Reviewers also note the compression design doesn’t grip most specialty bars well, so a separate collar is still needed for trap/axle-style bars.

What is a Collar?

What barbell collars are

Collars (clips) lock the plates onto a barbell’s sleeves so they can’t slide or rattle off — a safety essential, especially for pressing and Olympic lifts. The common types: cheap spring clips, quick lock-jaw / quick-release collars (the everyday favorite — fast and secure), and competition collars (precision-weighted, 2.5 kg each, for calibrated meets).

What to look for

A secure clamp that won’t creep under drops or high reps, quick on-and-off operation, and a fit for your bar’s sleeve diameter (standard Olympic is 50 mm). For most home gyms, a pair of lock-jaw-style collars is the right balance of speed, grip, and price.

A USA-made nylon barbell collar built specifically for chain and band training — each collar ships with a 0.625” carabiner so chains clip directly to the bar instead of being looped through a spring collar. Its standout dimension is functionality: reviewers across manufacturer, retail, and independent video reviews agree the collar locks down solid, goes on and off with a quick hand turn, and makes swapping chains or bands fast — one long-term reviewer calls it his most-used collar with almost no wear after a year. The weak spot is versatility: the compression design doesn’t grip most specialty bars well (reviewers note needing a separate collar for trap/axle bars), and the thick nylon body, while rated to 675 lbs of chain per side, draws some durability skepticism next to metal lever collars. A solid, purpose-built pick for anyone doing regular chain or band work on a standard Olympic bar.

+Functionality: locks down solid and makes loading/unloading chains or bands fast with a quick hand turn (manufacturer; Rogue customer reviews)
+Functionality: includes a 0.625" carabiner on each collar so chains attach directly without threading through the collar (manufacturer)
+Durability: one reviewer reports almost no wear after more than a year of regular use as his primary collar (YouTube: Joe Gray)
+Build quality: 1.5" thick nylon body rated by the manufacturer to hold up to 675 lbs of chain per collar (manufacturer; Rogue customer review)
+Versatility: usable for more than chain work -- one reviewer used the carabiner to attach a landmine-row handle (YouTube: DEFYfitness)

−Versatility: compression design does not grip most specialty bars well, requiring a second collar on the outside for trap/axle-style bars (YouTube: Joe Gray)
−Durability: thick nylon construction draws some skepticism on long-term durability compared to metal lever/compression collars (YouTube: DEFYfitness)
−Build quality: no magnetic rack-storage option, unlike some competing premium collars (YouTube: DEFYfitness)
−Value: no independent expert-outlet review (e.g. Garage Gym Reviews, Garage Gym Lab) found scoring this specific model -- available coverage is manufacturer/retailer copy and two YouTube reviews
