fischer Ventilation Duct Clamp LGS: Secure Airduct and Metal Roof Fixing

Applications

2-screw-pipe clamp with sound insulation for fixing of spiral ducts.
For use in dry interior areas.

Advantages

The large opening angle of the LGS enables a quick and easy installation.
The LGS's two screws allow the adjustment to suit the outer pipe diameter.
The sound insulation insert offers noise protection and prevents contact corrosion.
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.

Installation

Installation LGS with connection nut

Diagram showing the installation of the LGS clamp using a single connection nut. The clamp is positioned around a ventilation duct, with the two screws and the connection nut mechanism clearly visible for tightening and adjustment.

Installation LGS with two threaded rods (for LGS ≥ 450mm)

Diagram illustrating the installation of the LGS clamp for diameters of 450mm and larger, utilizing two threaded rods. The clamp is shown around a duct, with two threaded rods attached via nuts on either side, enabling a doubled recommended load capacity.
