Abstract
A truss, having an integral hold down strap, which can be attached to a wall of a structure. The truss contains an upper and lower chord and typically contains web members that extend between the upper and lower chords to provide strength and rigidity. The lower and upper chord converge at the heel of the truss and are connected by at least one nailing plate. The hold down strap is an elongate piece of sheet metal which is smooth and free of teeth, and has a first portion which contains two opposing flanges that are bent such that the first portion has a generally U-shaped cross section. The hold down strap also has a second portion sized to extend from the first portion and into engagement with one of the other structural components of a wall. The first portion of the hold down strap is sized to engage the end surface of the lower chord with the two opposing flanges engaging the side surfaces of the lower chord. The hold down strap is attached to the lower chord with a nailing plate, typically with the same nailing plate that connects the lower chord to the upper chord member.
