How roof trusses work: Triangles are naturally rigid geometric shapes that resist being distorted when pushed on.

    The FallTech® Permanent Truss Roof Anchor discussed in this manual is designed to provide an easily installed anchorage for persons working at height on wood structures and subject to fall hazards. The anchor consists of stainless steel, with installation holes and an 11/16”File Size: 4MB. Trusses are made up of four main parts. The upper angled parts correspond to the common rafters used in stick framing roofs. These pieces are known as upper cords and there are two of them in each truss. The bottom horizontal of the triangular truss form, which corresponds to the joists in stick framed roofs, is known as the lower cord.
