Tamtorque sign fixing clamps have been designed for clamping signs of all types to round, square, hexagonal or any unusual shaped post, giving a quick and reliable fix every time. Removes the need to cut the band to size. They do not therefore have sharp edges which can snag or cut and, unlike other banding systems, can be easily reused or readjusted. Tamtorque sign fixing clamps are manufactured from high strength stainless steel and have a hardened tamper resistant screw with a unique recessed seven sided socket. This means that they can only be tightened or released with a special Tamtorque driver An auto locking safety buckle ensures the free end of the band is both safe and tidy.
