MiTek Top Plate Stiffener

MiTek Top Plate Stiffener is an engineered G300 galvanised steel bracket designed to reinforce timber wall top plates at truss bearing points. By distributing the concentrated roof loads applied at truss locations, it helps prevent localised plate splitting, rotation and crushing, improving the structural performance and compliance of timber wall framing systems.

Overview

• Engineered top plate stiffening bracket by
• Designed to reinforce timber top plates at truss bearing locations
• Helps resist localised crushing, splitting and rotation at concentrated roof load points
• Manufactured from G300 steel with Z275 galvanised coating
• Suitable for residential and light commercial wall framing systems

Key Features & Benefits

• Reinforces top plates under concentrated truss loads — reduces risk of splitting and plate failure
• Helps resist rotation and localised crushing at truss bearing points
• Improves load transfer from trusses into the wall framing below
• Quick, simple face-fix installation alongside truss tie-down connectors
• Engineered performance provides consistent, reliable results versus site-built solutions
• Designed to meet relevant Australian framing standards

Applications

• Under roof truss bearings on timber wall frames
• Wall top plates subject to high concentrated or uplift roof loads
• Loadbearing wall systems requiring additional plate reinforcement
• New builds and structural upgrades to existing timber framing
