Pack of 1 x 20mm Woodworking Clamps - Dog Hole - Quick Action - For Office Workbench - Quick Fixing Clip

Three-speed adjustment (high, medium, and low) provides different clamping forces to suit various working conditions. The quick-release clamp is made of high-quality aluminum alloy and stainless steel for maximum durability and strength. The maximum clamping height is 60 mm, and this can be adjusted according to the thickness of the board. Clamping is quick and easy: simply insert the clamp into the workbench's mounting hole, secure the wood to the clamp, and press the gears. This makes clamping easier and reduces hand fatigue. For best results, use with a workbench with a thickness of 20 to 40 mm (maximum clamping 60 mm). Drill a suitable vertical hole in the top of your workbench and slide the clamp into the hole.
