Five reasons lifters switch to Forge collars
Machined, not moulded
Aluminium holds its clamp shape where plastic eventually flexes and cracks.
Rubber-lined grip
Natural rubber grips the bar's knurling without scratching the finish.
One-pull closure
A single lever pull clamps or releases, no twisting or threading needed.
Fits standard bars
Sized for the 28 to 32 mm sleeve diameter found on most Olympic barbells.
Built for repeat use
Designed to be clamped and unclamped daily without the mechanism wearing loose.
How it arrives
Each pair ships in a branded Ironclad Fit sleeve with the collars nested together to prevent rattling in transit. No loose plastic bags or extra packaging to unwrap.
From first clamp to a hundred sessions in
First clamp
You notice the plates stop shifting even on your heaviest set of the day.
Becomes automatic
Fitting the collars turns into a quick habit before loading any bar.
Still holding firm
The clamp tension hasn't loosened despite daily loading and unloading.
Machined, not moulded
Collar questions, answered plainly
Will these fit any standard barbell? +
Yes, they're sized for standard 28 to 32 mm Olympic bars, which covers the vast majority of home and gym barbells.
Do they mark or scratch the bar's finish? +
No, the rubber lining sits between the aluminium clamp and the bar, so there's no metal-on-metal contact at the grip point.
How much weight can they hold in place? +
They're built to hold a fully loaded bar for squats, deadlifts and bench press without the clamp loosening mid-set.
Can I use just one collar per side? +
You can, but using a pair keeps the load balanced evenly on both ends, which is why we sell them as a set.
What lifters say after using them
"The clamp clicks shut so fast I don't even think about it anymore between sets."

"Solid build, fits my home barbell perfectly, just wish the box was a bit smaller for storage."
