The Faithfull Aluminium Quick Action Sash Clamp - 36in offers a lightweight yet strong alternative for light to medium duty clamping tasks. It is constructed from a 'U' box section of aluminium extruded bar and fitted with a cast head and foot. The quick-release slide allows the clamping capacity to be adjusted instantly in 25mm increments along the bar. Deep cut acme threads on the main screw and a sturdy tommy bar provide a powerful and rapid clamping action.
