The Quick-Release Fasteners for Dumbbell Bars 

30/31 mm

The quick-release fasteners for dumbbell bars 30/31 mm from Gorilla Sports ensure the integrity of your body during your workout. The specially developed click system holds the weight plates where you have placed them, preventing them from slipping down during a lift. This allows you to concentrate on what's important - you and your training.

The Facts About the Quick-Release Fasteners for Dumbbell Bars 30/31 mm :

  • Suitable for barbells, dumbbells and curl bars with a 30/31 mm mounting diameter
  • Black/red colour scheme
  • Material: plastic, rubberised inside
  • Integrated rubber coating ensures a secure hold and prevents the weights from slipping
  • Supplied in pairs so you can start training straight away
  • Click system enables weight discs to be changed quickly

What Else Is Interesting About the Quick-Release Fasteners?

The dumbbell quick-release fasteners are designed so that you can open and close them quickly and easily, so you don't waste time between sessions. The special click system makes it possible. The integrated rubber coating on the inside holds firmly on bars with the standardised dimensions of 30/31 mm. So make sure that the diameter of your barbell is the right one. As you can see, there was hardly any good reason to train without a safety catch before, but thanks to the quick-release fasteners, you can now train completely on the safe side.

What matters is the diameter of your bar: Olympic collars fit onto 50/51 mm receptacles, standard collars onto 30/31 mm bars. Check before buying which system you have, since these sizes aren't compatible. All variants are conveniently delivered in a 2-piece set for both bar ends.
The spring collar is compressed and pushed on, it's light and lightning-fast to change, but clamps with limited force. The star collar is screwed onto a thread or sleeve and holds even heavy loads backlash-free, but takes a bit more time. Quick-release collars with clamping levers combine both: firm grip and plate change in seconds, ideal for sets with frequent weight changes.
Always position the collars directly on the plates and check the secure fit before every set, especially during dynamic exercises like cleans or rows. Keep the clamping surfaces and bar sleeves clean and free of grease so nothing slips. Worn-out springs or damaged clamping levers need to be replaced - a collar is a safety component.
They work with barbells, dumbbells, and curl bars that have a grip diameter of 30/31 mm.
The click system keeps the plates reliably in position, while the rubberized inner side provides extra secure grip and prevents slipping.
