Installation

• Use all specified fasteners.

The following installation methods may be used:

• Top-Flange Installation The straps must be field formed over the header 2″ minimum. Install top and face nails according to the table. Top nails shall not be within 1/4″ from the edge of the top-flange members. For all top-flange max conditions, nails used for joist attachment must be driven at an angle so that they penetrate through the joist and into the header. For top-flange min installations, straighten the double-shear nailing tabs and install the nails straight into the joist. Top-flange max installations require full backing to allow for joist slanted fasteners to be properly installed.
• Face-Mount (Min.) Installation Install face nails according to the table, with at least half of the required fasteners in the top half of the header. Not all nail holes in the straps will be filled. Nails must have a minimum 1/2″ distance from the edge. For nailer and truss-to-truss installation, straighten the double-shear nailing tabs and install the joist nails straight into the joist. The face-mount (min.) installation option accommodates conditions where the supported member hangs either partially or entirely below the header.
• Face-Mount (Max.) Installation Install face nails according to the table. Not all nail holes in the straps will be filled. The lowest four face holes must be filled. If needed, the straps may be bent over the top of the carrying member. The required face nail quantity from the table may be distributed between the face and top of the header. Nails used for the joist attachment must be driven at an angle so they completely penetrate the corner of the joist into the header.
