What is a SlideBelts brand ratchet belt? It’s a belt that lets you freely adjust your belt size without the limitation of holes in the strap. In fact, there are no holes at all! A tab in the buckle catches on a row of notches sewn onto the underside of the strap, allowing for over 30 size options with 1/4″ (6.35 mm) between adjustments. All SlideBelts come with a belt strap that can be trimmed to your exact waist size. The full length of one of our straps fits a 48″ (122 cm) waist size.
