This Dangler is made of sturdy 3mm thick black leather. The loop fits belts up to 2.25" wide, and the D-ring fits sheaths with belt loops up to 1.375" wide. Casstrom's No. 3 Dangler is a belt attachment that allows your knife to hang further down from the waist when sheathed. It offers easy access to your knife when wearing a jacket, and allows comfortable sitting without the knife getting in the way. The innovative D-ring carabiner makes attaching and detaching your knife quick and easy.
