BowTie HD | Helifix Structural Repair
The heavy duty BowTie HD is a 12mm diameter threaded bar with a self-cutting end used to secure the wall masonry to two or three parallel joists. Installed externally for minimum inconvenience, the BowTie HD is inserted through a clearance hole and then driven into the first and subsequent joists before being bonded into the masonry.
