A: Lay out ve (539) Rafter As and two (540) Rafter Bs on a hard at surface as shown in g. 8.1. You will need
lots of room for this step.
B: Place 1 (543) Strap Long on the bottom of the one (540) Rafter B, ush to the outside edge and four (539)
Rafter As, centred on the last. Be sure the wider gap on (543) Strap Long is on (540) Rafter B. Follow by placing
one (544) Strap Short then another (543) Strap Long and another (544) Strap Short in the same manner. Make
sure the assembly is square, pre-drill the rst (543) Strap Long with a 1/8” drill bit as shown below, then attach both
(543) Strap Longs with ten #8 x 1-3/4” Wood Screws per board and to both (544) Strap Shorts with six #8 x 1-3/4”
Wood Screws per board. The screws on the outside (539) Rafter A are inserted at an angle. (g. 8.1, 8.2 and 8.3)
C: Place one (541) Ridge Long on the angled ends of the rafters so the outside edges are ush then attach with
eight #8 x 2-1/2” Wood Screws. (g. 8.1 and 8.4)
