Truss Clip

STC truss clip is used to provide alignment control between a roof truss and non-bearing walls. They are manufactured from 1.1mm pre-galvanised steel. The 38mm slot permits vertical truss chord movement when loads are applied.

To allow for vertical truss movement, screws into the truss or rafter should not be driven completely flush against the connector.

1. Truss or rafter must be bearing on top plate to achieve loads under 'Without Gap'

2. Clips are required on both sides of the truss to achieve R4 loads (stagger parts to avoid screw interferences)

3. To allow for vertical truss movement, screws into the truss or rafter should not be driven completley flush against the connector

1. Truss to rafter must bear on top plate to acheive the allowable loads under 'without gap'

2. Clips are required on both sides of the truss to acheive F1 loads in both directions (stagger parts to avoid nail interferences)

3. Install slot nails in the middle of the slot. Nails should not be driven completley flush agsinst the connector to allow for vertical movement

4. Products not intended for floor applications due to the frequency of floor joist deflections and potential for squeaks

5. Allow up to 1.5mm gap between nail head and truss clip to prevent squeaking
