The Burmon Bracket (Australian Patent 2013209390) has revolutionized the way Floor joists are tied down to the bearers. Once you have done your set out, screw fix the brackets to the bearer. Then simply drop the joist inside the bracket and fix it off using the Burmon screws supplied - job done. The Burmon Bracket stabilises both sides of the joists ensuring a strong and stiff connection. The Burmon Bracket is faster and easier to install and has a higher tie down capacity than triple grips.
