Accessories

Brief description

Use the clamping bolt to convert existing quick-release skewers with a center hole in the base plate to the 20-mm hole pattern. Insert the stainless steel clamping bolt through the base plate of the clamp and secure it with the included M8 hex socket screw (SW 6) – then insert the clamp from above into any 20-mm hole. This allows you to use push-rod, vertical, or horizontal clamps, such as those from Bessey or AMF, on perforated and multifunctional tables.

The clamping bolt features a stepless, automatic leveling function of 13 mm—allowing the clamp to automatically compensate for minor differences in height. The bolt is made of stainless steel, and the cylinder screw is galvanized.

You can find additional clamping accessories for the 20-mm hole pattern in the lift table system.
