Woodworking vice type 52 1/2 – with speed clamping
This is how speed clamping works: Turn the vice handle counterclockwise (CCW) 1-1/2 to 2 times to release the speed nut from the main screw. The movable jaw can now be moved forward or backward as required. Turn the handle clockwise (CW) 1-1/2 to 2 times to re-engage the speed nut with the main screw. This allows you to tighten the vice in the normal way.
Keep your fingers out of the jaws when speed clamping!

Add a spacer panel in mounting area if worktop thickness is insufficient
Fix the vice with sufficiently large screws on a worktop that cannot tilt. Remember that this vice weighs nearly 16 kg! For the rear holes we recommend M12 through bolts with a hexagonal heads that are countersunk into the worktop from above. For the front holes (ie, the holes near the jaw) we recommend 12 mm wood screws with a hexagonal head, which are screwed in from below. The heads of the bolts and screws and the nuts should be fitted with washers. See diagram for details.
Shop-made wooden jaw liners are easily fixed to the jaws once the vice has been mounted. The jaws are provided with mounting holes. Countersink the screw heads on the jaw liners to avoid damaging clamped workpieces.
