Information

Construction tubes GN 990 can be supplied in any length up to 3000 mm.
The tolerances specified for the outside diameter of the round construction tubes comply with the requirements for split mono-block connector clamps. Otherwise the tolerances comply with DIN 2391, DIN 2395 and DIN 2462.
Two-piece connector clamps allow obviously larger tolerances on construction tubes.
