L/LS/GA REINFORCING AND
SKEWABLE ANGLES
|
The GA Gusset Angles' embossed bend section provides added
strength. Staggered nail pattern reduces splitting and allows back-to-back installation.
L--Staggered nail pattern reduces the possibility for
splitting and allows installation on both sides of a member. LS--Field-adjustable angles
attach members intersecting at angles.
MATERIAL: L--16 gauge; GA and LS--18 gauge
FINISH: Galvanized
INSTALLATION:
- Use all specified fasteners; see General Notes.
- LS--field skewable; bend one time only.
- Joist must be constrained against rotation (for example,
with solid blocking) when using a single LS per connection.

- GA and L angles--loads are for condition F1 or F2; LS
angles--loads are for condition F1 only.
- GA1 and GA2 angles--loads for F2 are 220 and 335 lbs (100)
and 280 and 415 lbs (125), respectively.
- Roof loads are 125% of floor loads unless limited by other
criteria; floor loads may be adjusted for other load durations according to the
code, provided they do not exceed those in the roof column.
- Loads are for one part only.
- Use a minimum lumber thickness of 1-3/4" For
1-1/2" lumber, use 0.81 of table load, except GA1 in F1 direction, use 185 lbs.
- Nail the L angle's wider leg into the joist to ensure table
loads and allow correct nailing, as shown in the illustration.
STC/STCT/DTC ROOF TRUSS CLIPS
For alignment control between a roof truss and nonbearing
walls; the 1-1/2" slot permits vertical truss chord movement when loads are applied.
MATERIAL:18 gauge
FINISH: Galvanized
INSTALLATION:
- Use all specified fasteners; see General Notes.
- Use STC or DTC depending on required loads. STC, installed
with Drywall Stop (DS), helps prevent fasteners tearing through the ceiling sheetrock (see
illustration).
- Use STCT where truss or rafter is separated from the top
plate of the nonbearing wall.
- Install slot nails in the middle of the slot.

- Loads may not be increased for short-term loading.
- Truss or rafter must be bearing on top plate to achieve the
allowable loads under "WITHOUT GAP."
- Installed with maximum 1/4" space between rafter or
truss and top plate under "WITH 1/4 GAP." Where loads are not required, space is
not limited to 1/2".
