Features

Material

  • Galvanized steel S250GD + Z275 according to NF EN 10346.

*

  • SFH rafter foot connectors are used to fasten rafter bottom chords to foot rails. The hole pattern in the rafter leg is designed so that the nails or screws on both sides do not interfere with each other. This makes the SFH type suitable for rafter widths of 40 mm or more
  • The SFHS/SFHM rafter foot connectors are used to fasten truss bottom chords to foot rails. They are suitable for truss widths of 95 mm or more—or multiple trusses with an individual width of 46 mm or more. A minimum dimension (W×H) of 160×60 mm for the foot rail was assumed during development
  • The SFHS/SFHM rafter foot connector is used when the load-bearing capacity of the SFM rafter foot connector is insufficient. They can also be used to connect rafters to foot purlins

Application

*

Support:

  • Wood, wood-based material

Supported member:

  • Wood, wood-based materials

*

  • The SFN / SFH / SFHM / SFHS rafter foot connectors securely join two pieces of wood positioned crosswise on top of each other to resist shear forces.
  • The shear force can act only in a specified direction.
