Strong and affordable, internal wall brackets are made of pre-punched and formed galvanised steel and are used to fasten roof trusses and interior walls. commonly known as IWBs, wall hitch brackets, or hitch brackets. With the help of these brackets' five 3.5 x 28.5 mm slots, the truss can shift vertically over time without putting additional strain on the wall. Additionally, the internal wall brackets prevent the top plates of internal non-load-bearing walls from moving laterally. The internal wall bracket may be fastened firmly to the wall plate using four 3mm drilled holes.
