Mark on the girder bottom chord (120mm minimum) the location of all girder brackets and hangers.
Position the High Load Girder Bracket against the bottom of the girder bottom chord and apply Multinail #14 screws.
Black Tip #14 screws must be applied until the underside of the screw head is against the girder bracket.
Do not over tighten the screws or use power drills that are too powerful for the job as this may damage the timber, screws or bracket.
- The High Load Girder Bracket is only provided with a structural adequacy certificate when used with Black Tip #14 screws
- TrusSourceTM provides diagrams and details of the girder bracket type and positioning.
Fix 12/25mm Black Tip #14 screws (6 per wing) to the girder truss.
Double Truss - Use 65mm long Black Tip #14 screws to fix to the double girder trusses
Triple Truss - Use 100mm long Black Tip #14 screws to fix to the triple girder truss
Fix 12/25mm Black Tip #14 screws (6 per side) to the supported truss to ensure that the uplift and anti-rotation features of the girder bracket is maintained
Note: The uplift in capacities are derived from AS1720-2010and are for houses where failure is unlikely to affect an area greater than 25m2. For primary elements in structures other than houses or elements in a house for which failure would be greater than 25m2 these capacities must be multiplied by 0.94. For primary joints in essential services or post-disaster buildings multiple by 0.88.
