The two-screw pipe clamp with combination connecting thread.

Pipe clamp FRS

The fischer pipe clamp FRS is a two-screw pipe clamp. The FRS is available as a electro-zinc plated version for use in dry interior spaces, zinclamella coated for use outdoors and stainless steel for use in corrosive environments. The two-screw version enables optimised adjustment in line with the outer diameter of the pipe. Together with the combination connecting thread M8/M10, this increases flexibility. This enables pipelines with an outer diameter of 12 to 219 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. (Fire protection valid for FRS and FRS zl). 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.

Advantages

The fire test report (for FRS and FRS zl) guarantees independently tested functional safety.
The two screws allow an easy adjustment to suit the outer pipe diameter.
The combination connecting nut with thread M8/M10 enables optimised mounting choices.
The sound insulation insert offers noise protection and prevents contact corrosion.
The screw's safety feature ensures trouble-free installation.
