Wire Buckles are designed to maximise their holding power and have an outstanding slip resistance with their “self-lock” feature. Featuring a small dent at the corner of the tensioning side allows the buckle to close tighter, making it more effective, durable, and less slippery. The Nitrated Wire Buckles is a type of wire buckle that features a blunt surface to provide enhanced protection to the belt surface. This makes the Nitrated Wire Buckles ideal for high load performance and handling. The buckles are also compatible with all container straps that we have available.
