Step 22: Attach Cross Support
Pre-drill all holes using a 3/16" drill bit before
installing the lag screws.
A: To adjust for uneven ground, raise or lower the
(221) Support Cross on the (213) SW Post. Make sure
the Support Cross is level prior to attaching with the lag
screws. (fig. 22.1 and 22.2)
B: Place (221) Support Cross between (213) SW
Posts at the previously determined spot and fasten with
1 (LS9) 5/16 x 4-3/4" Lag Screw (with flat washer) per
side. (fig. 22.2 and 22.3) Notice one side is fastened
on the outside and one on the inside. It is important
that each side is positioned exactly the same as the
diagram. (fig. 22.3) Tighten the lag screw when
you are sure (221) Support Cross is level.
C: Attach 1 (WB8) 5/16 x 2-3/8" Wafer Bolt (with flat
washer and t-nut) to (221) Support Cross through
the middle hole. (fig. 22.2 and 22.3) IMPORTANT!
MAKE SURE THE BOLT IS ATTACHED TO MINIMIZE
CHECKING OF WOOD.
