Anti Crush Plates



Anti Crush Plates provide improved bearing capacity for timber top plates.

The Anti Crush Plates are manufactured from 1.5mm galvanised steel and are:

  • Quick and easy to install.
  • Available in two profiles – left hand (LH) and right hand (RH).
  • A secure connection of trusses to wall plates.
  • An improvement to timber bearing capacities for heavier loads.


Anti Crush Plates are typically used in the following application:

Connecting Roof Trusses to Wall Plates


A minimum of 17/30mm x 2.8Ø Multinail nails must be used to fix each Anti Crush Plate for full tabulated values.
(8 nails into side of double top plates, 5 nails into the top of top plate and 4 nails into side of truss)

NOTES: The uplift in capacities are derived from AS1720-2010 and 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 multiply by 0.88.
