A heavy duty roller buckle in three sizes: 25mm (1in), 32mm (1¼in), and 35mm (1⅜in). Nickel plated, and formed from heavy wire - 5mm on the 35mm - so it's a good deal stouter than a standard roller buckle.
The roller runs the full width of the front bar, so the strap end slides over it without scuffing when you pull it tight. The pin hinges on the back bar between two stops that keep it centred, and the strap fastens through a punched hole. You'll want a keeper for the loose end. It suits work that takes a real pull - harness and tack, heavy belts, dog collars, and luggage straps.
The 25mm and 32mm are sold singly and in packs of five and ten. The 35mm is sold singly.
