38mm 2 Pack Heavy-Duty 316 Stainless Steel Lock Slider Buckles Heavy Strap Release Buckle Adjustable Metal Buckle Fasteners (1”inch)

The strap buckle for my trunk car battery broke. This works PERFECTLY. Solidly made. Spring tension on clasp keeps strap taut. Teeth on clasp are grippy, but do not damage strap.

Worked great for a strapping project in my camper. Good value, strong grip.

much better than plastic buckles of similar design ~

These straps slip on standard 1 inch nylon strap at around 40 lbs. Other brands I have ordered (not currently available) have worked to more force than I can apply. Probably over 300 lbs.

The illustration is not quite correct. The levers on the ones I received are almost flush rather than angling up, with less leverage, which makes them harder to thread and adjust. Otherwise they work OK and are more rugged than run of the mill buckles.
