The WP may be used for weld-on applications. The minimum-size weld is a 1 1/2"-long fillet weld to each side of the top flange; weld size to match hanger material thickness. See General Instructions for the Installer, note k for weld information. Weld-on applications have the maximum allowable capacity listed. Uplift loads do not apply to this application.

Non-modified hangers can support joists sloped up to 1/4 :12 using table loads. For joists sloping between 1/4 :12 and 3/4 :12 use 85% of the table loads. See technical bulletin Sloped Joist in Non-Sloped Hangers (T-C-SLOPEJST).

Web stiffeners are required for these hangers.

If joist is shorter than hanger by more than 1/2" use only 50% of the table loads.
