The 90° head fits around the Progrip’s fixed clamp head; the lugs on the moulding fit into the alloy rail extrusion to ensure correct alignment and are fastened securely with two self tapping screws. Attaching the 90º head greatly reduces the time taken to set up a square crosscut and also turns the guide clamp into a large square for marking out. The body is a strong glass fibre reinforced ABS moulding with a 175mm long face, 12mm deep. The textured face prevents slippage. For increased precision, align with an engineer square before clamping.

Attaching the 90° head to your guide clamp greatly cuts the time taken to set up a square crosscut. It adds another function to your Progrip guide as a large square for marking out.
