KeppiFitness Barbell Clips OPENCOLLAR
Bells of Steel’s Magnetic Clamp Collars are a slim, lever-clamp barbell collar built around two-sided magnets so the pair can stick to any painted metal rack surface — uprights, crossmembers, or feet — for tidy between-set storage instead of getting left on the floor or hung on a hook. A rubberized interior grips the sleeve firmly without scratching the bar’s finish, and at roughly 1” wide the collar is about half the width of a traditional twist-lever clamp, leaving more sleeve free for loading plates.
Independent testing backs up the core claims: one reviewer confirmed the magnets hold reliably on Rep and Titan rack finishes and that the clamp doesn’t slip even loaded and flipped upside down, fitting everything from standard Olympic bars to an axle bar and a safety squat bar. The same review’s biggest knock, echoed independently on r/homegym for the identical OEM design sold under other brand names, is a genuinely tight out-of-the-box fit — expect a week or so of repeated on/off use before it loosens enough for one-handed operation. It’s not compatible with narrower 1.89” specialty sleeves (e.g. Bells of Steel’s own Arch Nemesis Bar or Lever Arms), which need a standard 1.98” Olympic sleeve.

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).
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.

These lock down hard and stay put — testers report zero slippage even upside-down with plates loaded, and the two-sided magnets stick reliably to painted rack uprights and crossmembers (verified on Rep and Titan finishes). The catch is functionality’s own flip side: out of the box the clamp is extremely tight, to the point one independent reviewer needed gloves and about a week of repeated on/off cycles before it loosened to one-handed use — a break-in complaint echoed by r/homegym threads on the same OEM design sold under other brand names. Versatility is strong (fits standard 2” barbells, axle bars, and safety squat bars alike) as long as you’re not running a sub-1.98” specialty sleeve. Build quality is solid — a rubberized interior keeps the slim ~1” profile from marring the bar’s finish — but there isn’t yet independent evidence of multi-year durability.
