The clamping bore axes of the two-way connector clamps GN 132.9 are arranged at an angle of 90° to each other. They hold typical construction tubes with full surface contact over the entire cross-section of the bore.
At the screw locations z, the socket cap screws reduce the bore cross-section for clamping. Adapter bushings GN 290 can be used to reduce the bore cross-sections to a smaller diameter.
For clamping without tools, the socket cap screws can be replaced by the adjustable hand levers GN 911.9 listed in the table as accessories.
