Kee Klamp are tubular fittings that are galvanised iron castings manufactured to the requirement of BS EN 1562 & 1563. The tubing is slipped into the fitting and locked by a cup-ended socket set screw. A simple hexagon key is the only tool required to give a strong rigid joint. All components are produced in a range of sizes to suit steel tubing to BS EN 10255 (ISO 65) medium or heavy gauges and 17.5mm to 60.3mm outside diameter. Tube manufactured to other specifications can be used providing the steel is compatible with BS EN 10255 (ISO 65) and the wall thickness is not less than 3.2mm.
