Up to now clamping elements or bench hold-downs for joiner’s benches and workbenches suffered from the handicap that the shank was permanently joined to the hold-down component and as such could only be used with a single hole size. This resulted in several mutually incompatible systems. One workbench has 3/4 inch holes, another 20 mm holes, not to mention exotic configurations with 1 inch holes and more besides.
Bessey has now solved this problem by separating the hold-down component and shank. There are now clamping elements in various designs with fixed or variable throat depth, with composite handles as for screw clamps or T-handles and lever handles. All variants fit on the workbench adapters (sold separately), of which there are four with shaft diameters for 19 mm, 20 mm, 25.4 mm and 30 mm holes. If your workbench is provided with holes having just one of these diameters you will be able to use all clamping elements of this series. The clamping elements are simply inserted into the adapter and secured with a hexagon socket screw.
