Mini Hanger 47mm Material Pre-galvanised mild steel. Features A galvanised joist hanger that provides great support with ease of installation. Published performance values are based upon 3.75 x 30mm square twist nails being used throughout. Wider strap provides more surface area on the supporting timber and allows increased nail spacing, enhancing the performance of the critical hanger-to-support part of the connection. Minimum and maximum nailing schedules are stamped into the strap providing correct installation information for site operatives. Speed-prong holds the hanger in position to allow easier attachment. The installer no longer has to try to hold hanger, joist and nail with one hand and swing a hammer with the other! The model number and size is stamped into the seat of the hanger for easy identification, even after installation. (Other Building Supplies Available)
