Simpsons Strong-Tie Adjustable Truss Hanger - THA38, THA44, THA50, THA75 & THA100 Solid Joist Hangers Roof Connectors

Adjustable Truss Hanger

The THA is a one-piece joist hanger supporting trussed rafters and composite timbers from timber members. The THA can be installed with a number of fixing options, for greater load capacity. See table below for fixing options. Available in seat widths from 38mm to 100mm.

• Location tab allows easier alignment to the carrying member.
• Choice of installation specifications to suit wrap-over or face fix.
• Speed prongs enable positioning of the hanger without nails before completing the install.
• Nailing schedules are stamped into the strap to provide the correct information to site operatives.
• The distinctive wide strap enhances the performance of the critical part of the connection by increasing the nail spacing and providing greater bearing area on the supporting girder.
