OUTRIGGER FRAME ASSEMBLY
At this point, all outrigger rafters are assembled and all
1-Way connectors are attached to the assembled outrigger
base rails.
SITE COMMENT:
For proper assembly of the frame, a level
site is required for the base rail.
SETTING OUTRIGGER RAFTERS
WARNING:
Rafters can be heavy and awkward to
handle. Use caution and adequate assistance when
setting the rafters in position.
Gather the parts:
• Outrigger rafter and base rail assemblies
• 1.315" pipe for purlin
• Connection plates (#105087)
• Tek screws and nut setter (3/8'' x 2-9/16 magnetic)
The following steps describe one way to assemble the
outrigger frame.
1. Position the base rail parallel with the main frame
assembly.
2. Lift one rafter into position and set the leg on the first
1-Way connector at one end of the base rail.
Move the base rail as needed so the
upper end of the
rafter
rests against the rafter leg of the main (or center)
frame assembly. Brace the first rafter in place so that it
will not fall or move.
WARNING:
TO PREVENT DAMAGE OR INJURY, DO
NOT LEAVE THE RAFTER UNATTENDED.
3. Secure the rafter leg to the 1-Way connector on the
outrigger base rail using two Tek screws. See the
diagram below.
ATTENTION:
Install Tek screws through the rafter
leg and into the 105088 connector.
Tek screws must
secure the rafter to the 105088 connector.
See the
diagram under Step 1 on the previous page.
NOTE:
Do not install
screws on the side of the
rafter leg where the metal
panels will be attached
later in these instructions.
Verify that the Tek screws
are secured to one of the
three sides of the 105088
connector.
4. With the first rafter secured to the outrigger base rail,
realign the base rail and rafter with those of the main
frame as needed and locate two (2) connection plates
(#105087).
5. Position the first connection plate (1) on the assembled
rafter as shown and secure it using Tek screws.
6. After attaching the first plate, attach the second
connection plate (2) to the remaining side of the rafter.
7. After anchoring the first rafter to the main frame
assembly, set the second rafter in place and secure
the upper end to the
rafter leg of the main frame
as
described in Steps 4-6 above.
8. Take one, swaged section of pipe (#131S075) used for
the purlin and slide it through the pipe straps on the two
rafters as shown below. Loosen straps if needed.
