Base clamps BKG of die-cast aluminum have a clamping point machined with cutting methods without a clamping slit.
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 structural tubes with full surface contact over the entire cross-section of the bore.
A grub screw with a cup point acts radially at the screw point to reduce the cross-section of the bore. The bushing into which the grub screw is inserted is made of red brass.
A centering bore on the clamped tube prevents pressure points and enables precise positioning.
