Base clamps BE of precision-cast stainless steel have a slitted clamping point machined by cutting methods.
The base flange with four bores serves as an interface or for fastening the clamp to the place of use.
The bore at the clamping point is arranged perpendicular to the face of the flange. It receives typically available construction tubes with full surface contact over the entire cross-section of the bore.
At the screw point, a carriage bolt and a cap nut or an adjustable hand lever reduces the bore cross-section for clamping. Type B features seals at the screw point.
Adjustable hand levers are intended for repeated, tool-free clamping. Under the designation HEK, these are available separately for individual use and in other designs. Compared with the tool-operated hex socket cap screw, the clamping force achievable with an adjustable hand lever is lower due to the shorter lever length.
