A cast roller buckle for 25mm (1in) straps. Nickel plated, with a squared, flat-faced frame.
The strap folds round the heel bar, where the pin hinges, and fastens through a punched hole. The roller on the front bar lets the strap pull through without scuffing. A cast frame keeps its shape better than a wire one, so it suits bridle and halter work, dog collars, bag straps, and narrow belts. You'll want a keeper for the loose end.
