Applications

2-screw-pipe clamp without sound insulation for fixing of spiral ducts.
For use in dry interior areas.

Advantages

The large opening angle of the LGSN enables a quick and easy installation.
The LGSN's two screws allow the adjustment to suit the outer pipe diameter.
The screw's loss protection prevents loss of the locking screws during installation.
Connection nut with combination thread M8/M10.
The LGS is drilled on both sides of the clamp from 450 mm diameter on. This allows for connection with two threaded rods with nuts. Thereby the recommended load of the clamp can be doubled.

Properties

Material: steel DC01 (material no. 1.330) according to DIN EN 10130
Zinc plating: electro zinc-plated
Connecting nut: resistance welded domed nut, M8 / M10, SW13
Locking screw: cross recessed pan-head screw M6 (up to size 400), hexagon screw with nut M10 (size 450 to 1250)
Fire behaviour: DIN 4102: Class A1
