LSSH Slope/Skew Hangers
The LSSH series connects rafters to ridge beams in vaulted roof
structures. This series is eld adjustable to meet a variety of skew
and/or slope applications. Slopes and skews 0° to 45°.
Materials: See chart
Finish: G90 galvanizing; LSSH15-TZ – G-185 Galvanizing
Options: See Chart for Corrosion Finish Options
Codes: See page 11 for Code Reference Chart
Installation:
• Use all specied fasteners. See Product Notes, page 17.
Steps:
1. Position LSSH connector against plumb-cut end of joist. Fasten
joist side anges on both sides with 10d (0.148") x 1-1/2" nails.
Bend seat up to t against joist bottom and drive (1)
10d (0.148") x 1-1/2" nail through bottom seat into rafter
bottom. Drive (2) 10d (0.148") x 1-1/2" nails at downward angle
through dimpled nailing guides.
2. Lean connector and rafter end against ridge beam at desired
position. Install specied 10d (0.148" dia. x 3") or 16d (0.162 x
3-1/2") nails through nail holes into ridge beam at right 90° angle. If
skewing the rafter, only drive nails into ridge beam on inside ange.
3. Bend ange to desired angle.
4. Hammer outside ange until edge touches header. Fasten outside
ange to ridge by driving specied 10d (0.148" dia. x 3") or 16d
(0.162 x 3-1/2") nails through nail holes.
• Web stiffeners are required for all wood I-Joist installations.
• Designer may consider adding a tension restraint for the
supported member for roof slopes exceeding 6/12. Refer to
pages 95-96.
