Pipe clamp FRS

The two-screw pipe clamp with combination connecting thread

The fischer pipe clamp FRS is a two-screw pipe clamp made from zinc-plated steel in material quality DD11 with an M8/M10 combination connecting thread. The two-screw version enables optimised adjustment in line with the outer diameter of the pipe. Together with the combination connecting thread, this increases flexibility. This enables pipelines with an outer diameter of 12 to 168 mm to be securely fixed with a threaded rod or stud screw indoors in accordance with the fire protection requirements of fire resistance class R 120 and MLAR. With a chlorine-free and silicone-free sound insulation insert, the pipe clamp meets the requirements of DIN 4109. The fischer FRS is suitable for applications in the temperature range from -40°C to +100°C.
