Freer Tool & Supply is Michigan's authorized DESTACO distributor for variable stroke straight-line action clamps—from our Clinton Township facility, we offer the complete F, FL, FO, and G series designed to accommodate workpiece thickness variation, tolerance stacking, and multi-part family fixtures without manual spindle adjustment. Variable stroke clamps feature rapid-adjust plungers that automatically compensate for part height differences up to 100-300mm (4"-12"), eliminating the time-consuming spindle threading required by standard straight-line action clamps.
