LVL RAFTER Tie Down CONNECTOR

THE SUPERIOR TIE DOWN CONNECTOR FOR LVL RAFTERS

PRODUCT CODES:
BCB45x45SCREW  BCB70x45SCREW BCB90x45SCREW


The Burmon Bracket (Australian Patent 2013209390) has revolutionized the way LVL rafters are tied down to the top plate/beam. Once you have done your set out, screw fix the brackets to the top plate/beam. Then simply drop the rafter inside the bracket and fix it off using the Burmon screws supplied - job done. Builders who prefer to use LVL rafters over trusses until now, have not had available a tie down connector that has been specifically designed to tie down 45mm wide rafters. The Burmon Bracket is faster and easier to install and has a higher tie down capacity than triple grips and straps.
