These roller buckles are designed to accept a small padlock through the tongue of the buckle, thereby making it impossible to remove whatever strap it is on. However, it is not necessary to use a lock if it is not wanted at that point, as the tongue functions as a regular tongue as well. These have many different uses, and are perfect when a moderate degree of security is desired (naturally, the thief could always cut the leather). To utilize this buckle you will need a oval punch to make the proper size holes in the strap. This is now available only in a single size, the larger in the photo, the 1". |
