The clamping bores of the flanged two-way connector clamps GN 134 are not machined and specially designed for construction tubes GN 990
or DIN 2391, DIN 2395 and DIN 2462 respectively.
The square designs are also suitable for use in profile systems.
Bores and square bores of the same nominal size can be assembled in any combination. For instance, nominal size 20 has the following combination options: B20-B20, B20-V20, V20-B20 and V20-V20.
The standard clamping screws are socket cap screws DIN 912. They can be replaced by adjustable clamping kits GN 911
(article code see table of dimensions).
