Pre-assembled triangle bracket STFN Fischer

What it is

The preassembled STFN Fischer triangle is a modular element for building support structures and frames in building services and construction. The pack contains 5 pieces, complete with 20 RHS M8 x 20 hammer-head screws in A2 stainless steel and 20 MU F M8 A2 flange nuts, for immediate assembly without additional components. Each element has a Ø 9 mm hole d and a cross-sectional area of 3.78 cm², and must be tightened with an installation torque of 10 N·m using a 13 mm spanner, with an M8 thread.

These components are used to mount photovoltaic systems on pitched and flat roofs: aluminium profiles, hooks for tiles and pantiles, tilt-angle brackets, bases and module fixing systems.

What it is for

Used for general-purpose fixing into masonry, concrete and timber, for installing building services and plant and for erecting steelwork and structural carpentry.

How to use it

First fix the structure to the roof, with hooks or bases suited to the roof covering, and then fit the profiles and modules with the clamps provided. Observe wind and snow loads and ensure watertightness at the drilled points. Work at height with fall protection.
