Spectre SP-18000 Pair of 1200mm (48in) Sash Clamps / Sash Cramps

Cold drawn steel bar -greater tensile and yield strength than standard hot rolled steel.
Fast action rolled thread applies pressure quickly and smoothly to the workpiece.
Flat bottomed head and slide enable the clamp to stand without support.
Slightly tapered jaws enable perfectly parallel clamping.
Coarse adjustment locating holes along the bar spaced at approximately 80mm, through which the steel pin passes to fix the clamp. Fine adjustment to the required clamping capacity is taken up with the 100mm lead screw. Note: The coarse adjustment holes are approximately spaced so the pair will not be matched, any variance will be taken up with the fine adjustment screw.
Precision machined slide glides quickly along the bar for set up.
