GN 276 and GN 278. For the version with stepless adjust- ment (Type S) swivel clamp connectors with centering step are used. Within the identical swivel width „b“, all bores „d 1 / d 2 “ can be combined as required. The clamping bores are mechanically machined and designed for GN 990 or DIN 2391, DIN 2395 and DIN 2462 construction tubes. At the screw locations z 1 , the socket cap screws reduce the bore cross- section for clamping. For clamping without tools, the socket cap screws can be replaced by the adjustable hand levers GN 911 listed in the table as accessories. see also... • Construction Tubes GN 990 → Page 1835 Information • Aluminum - - Powder coated Black, RAL 9005, textured finish SW - - Plain, matte shot-blasted BL • Socket cap screws DIN 912 Stainless steel AISI 304 • Hexagon nuts DIN 985 Stainless steel AISI 304 Self-locking via polyamide ring • Stainless Steel Characteristics → Page 2166 • RoHS Specification 5 • Adjustable Hand Levers GN 911 → Page 1784 Accessory
