ATX Magnetic Barbell Collars

The ATX Magnetic Barbell Collars are compact locking collars for Olympic 50mm barbells that clamp on with a large single-hand lever and hold via a rubber-lined bore. Their defining feature is a set of integrated magnets on the outer face, letting each collar stick to any steel rack upright, machine frame, or other metal surface for storage instead of getting left on the floor. An extra-slim, narrow profile keeps as much sleeve length as possible free for weight plates, which is especially useful on Olympic dumbbells with shorter sleeves. Built from break-resistant polyurethane rather than metal, the pair weighs about 250 grams total. The SKU appears to be discontinued – ATX’s own product page no longer resolves, and at least one regional retailer lists it explicitly as discontinued – so buyers may find sourcing a replacement pair increasingly difficult.

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.

The ATX Magnetic Barbell Collars are compact 50mm compression collars with an integrated magnet, letting them stick to any steel rack upright or machine frame instead of getting lost on the floor. Its standout dimension is functionality: the large single-hand lever, extra-slim profile that preserves plate-loading space, and rubber-lined bore all check out consistently across five independent European retailer listings, and the one verifiable customer review calls them “quick and easy” with a strong hold on the rack. Its weakest dimension is durability/availability – there’s no independent long-term testing or editorial review of this specific SKU, and it now appears discontinued (the manufacturer’s own product page 404s, and Sam’s Fitness AU lists it outright as DISCONTINUED), so buyers may find it hard to source going forward.

  • +Functionality: large lever allows one-handed locking/unlocking, confirmed consistently across five independent retailer listings (The Gym Revolution UK; motionsports.de; Sam's Fitness AU; Pullum Sports UK; Megafitness DE)
  • +Functionality: magnetic back lets the pair stick to any rack upright or steel surface for storage, the core selling point echoed by every source including the one real customer review ("stick to powerack" -- Pullum Sports UK)
  • +Versatility: extra-slim/narrow profile (92mm wide, 250g per pair) leaves more usable sleeve length for plates than a bulkier collar, useful on Olympic dumbbells with short sleeves (manufacturer; The Gym Revolution UK)
  • +Build quality: rubber lining on the inner bore protects the barbell finish from scuffing, a detail repeated across manufacturer and retailer copy (manufacturer; motionsports.de)
  • −Durability: no independent editorial or video review exists for this specific SKU -- every data point beyond specs traces back to manufacturer/retailer marketing copy or a single customer testimonial
  • −Value: appears discontinued -- the manufacturer's own atxfitness.com product URL now 404s, and Sam's Fitness AU lists the item outright as DISCONTINUED, making long-term availability and warranty support uncertain
  • −Functionality: reviewer sample size is a single five-star testimonial (n=1) on Pullum Sports UK -- too thin to confirm the magnetic hold or lever durability hold up over months of use
  • −Build quality: constructed from PU plastic rather than metal, so it lacks the all-metal build some lifters prefer for extreme durability under heavy daily use (manufacturer specs)
