MSSHL/R Severely Skewed Hangers
MiTek’s MSSH217 hanger accommodates a skew range of 60° to 85° (30° maximum off
the girder) without the need for a more expensive custom design hanger. Face nail to
webs or bend the ange strap over the chord. Available in left (L) or right (R) congurations.
Materials: 18 gauge
Finish: G90 galvanizing
Installation:
• Use all specied fasteners. See Product Notes, page 18.
• The 3 lower holes on each strap are for top nailing when the strap is bent
over the truss chord. These holes are not for face nailing.
• One or both straps may be bent over the bottom chord of the girder with
top or backside nailing.
• Note: Select the correct (right or left) hanger so that the strap on the outside
of the angle will pass the end of the truss. When facing the hanger, the strap
in the rear turns in the direction of the skew. The front strap turns to pass
behind the end of the carried member.
• Attach the hanger at the end of the truss with a single 10d (0.148" dia.) x
1-1⁄2" nail into the side ange or bottom.
• Place the truss in position against the girder. Push the outside strap past the end of the
truss to the girder web and face nail through the top 8 holes with 10d (0.148" dia.) x 1-1⁄2"
nails for a 1-ply girder, or 10d (0.148" dia. x 3") common nails for multiple-ply girders.
• The strap inside the angle can be formed over diagonal webs (if design allows) or
bend over the girder chord. Use two nails into the top and/or back side of the girder.
• If the outside strap does not contact a web, bend the strap tightly over the girder
chord. Use two nails into the top and/or back side of the girder.
• For uplift resistance, other means of attachment are required. If both the truss
and girder have vertical webs, attach a scab to pack out the girder web nearly
ush with the truss web and use a eld adjustable MP framing angle across
the two. A top chord connection for uplift requires a at LSTA strap tie wrapped
under the girder and over the truss chord.

3) Maintain minimum 3/4" edge distance when installing nails.
4) The supported member shall be supported by blocking or other means to prevent rotation.
