The fixed bracket and pressure plate are made of one piece, heat-treated and torsion-resistant, with 38 mm wide movable pressure plate and a functional grid mechanism for vibration-proof clamping. Particularly useful in confined working conditions. Quick conversion of the sliding clamp for spreading applications by reversing the clamping rail and the additional block is done in two steps. The one-finger quick clamp and release lever makes clamping up to five times faster than with conventional clamps. The clamps are designed for wood and steel applications. Clamping force max. 460 kg with a clamping width of 254 mm. The throat depth is 121 mm. The cross section of the fixed clamp is 122 x 11mm. With an M10 thread.
