Barbell Collars & Accessories

5 products

Barbell collars hold your weight plates on the bar. A secure collar prevents plates from sliding or shifting during a lift, protecting both you and the people training around you. Whether you need a basic pair of spring collars for a home gym or calibrated competition collars for a weightlifting platform, the right collar keeps plates locked in place.

Our range covers spring collars, nylon locking collars, magnetic locking collars and calibrated competition collars. All collars in the range are designed for Olympic (50mm) or Standard (28mm) bar sizing.

Since 2009, Little Bloke Fitness has supplied Australian home gyms, PT studios and commercial facilities with barbell accessories built for long-term use. Our range is available to view in our Melbourne showroom and ships Australia wide.

Barbell collar FAQs

That depends on your barbell. Olympic barbells (the most common in gyms) use 50mm sleeve collars. Our standard barbells use 28mm collars, although the diameter of standard bars can vary between 25mm and 20mm. Check your bar's sleeve diameter to confirm the right size.

Most of our barbells are supplied with basic collars. Check the individual barbell listing to confirm what's included. Replacement and upgraded collars can also be purchased separately.

Spring collars are simple, affordable and quick to use. Locking collars use a clamp mechanism that holds firmly on the sleeve and can be particularly useful for Olympic lifting, higher-repetition training or anywhere you want a more positive locking mechanism.

For general training, standard spring or locking collars are normally all you need. Calibrated collars are used where the weight of the collars forms part of the total loaded weight, such as powerlifting and weightlifting training. Our 1RM calibrated collars weigh 2.5kg each and are calibrated to within ±10g.
