The Lock-Jaw One is a simple barbell collar set made for standard 1-inch / 25mm bars. If you use smaller bars at home and want something quicker than basic spin locks or spring clips, this pair is designed to clamp on fast and stay put during regular training.
With a single-action cam lock, an injection-moulded nylon frame and thick pressure pads, it aims to offer a secure fit without being awkward to use. It is sold as a pair, so you get a full set ready for one bar.

For home gym buyers, the main appeal here is convenience. The quick latch design should make plate changes faster, which is helpful for circuits, lighter strength work and general training sessions where you do not want to keep fiddling with collars between sets.
It is also built specifically for smaller 1-inch bars, so it is worth checking your bar size before buying. The moulded pressure pads are intended to clamp securely while also being kinder to chrome bar coatings than harsher metal-on-metal options.
- Fits standard 1-inch / 25mm weight bars
- Single-action cam lock for quick fastening
- Sold as a pair
- Nylon frame with thick moulded pressure pads
- Suitable for general weight training and wider athletic use
If your home setup uses 1-inch bars rather than Olympic bars, these collars look like a practical upgrade over very basic clips. They should suit anyone who values quick changes, straightforward handling and a more secure feel for everyday workouts.
The main thing to keep in mind is compatibility, as they are made for 25mm standard bars only. For the price, the Lock-Jaw One seems like a sensible choice for home users who want an easy-to-use collar set without overcomplicating their setup.
