Roof Truss Tie Downs for Wood Frame

THE REVOLUTIONARY ROOF TRUSS TIE-DOWN SOLUTION

Product codeS:
BCBS70x35SCREW & BCBS90x35SCREW


The Burmon Bracket (Australian Patent 2013209390) is specifically designed to tie down roof trusses to wall frames for Australian and International Building Systems and is fully certified and tested for use in accordance with AS1684 Residential Timber Framed Construction. The revolutionary design enables the Bracket to be securely fixed directly to the top plate. Using a cordless impact driver, simply attach the bracket to the top plate using Burmon panhead screws. The truss is then placed inside the bracket and fixed using Burmon roofing screws. This finishes the tie down of the trusses eliminating the hassle of going back later to nail off connectors. The Burmon Bracket is faster and easier to install than ordinary conventional connectors whilst delivering a stronger tie down over the whole roof.
