STEP 5

-Begin rafter hanging bracket installation by snapping a level chalk line along the wall to locate the bottom of the rafters.

To determine the height of the line, simply add the height of the posts and the height of the header.

-Locate and mark a centerline on the wall for each rafter hanging bracket adjacent to the rafter mounting brackets on the header.

-Pre-drill (2) 5/16" holes in the wall, being sure to hit a solid anchor point. Attach a rafter hanging bracket to the wall using

(2) 1/4" x 1 1/2" lag screws and lag screw inserts.

NOTE: If a solid anchor such as a wall stud can not be located, a ledger board may be required (not supplied by manufacturer).

-Attach a rafter seam side up to the bracket using (4) #8 x 3/4" HWH #2 Tek screws (see Fig. 5-1).

-Attach the rafters to the rafter mounting brackets using (4) #8 x 3/4" HWH #2 Tek screws per bracket (see Fig. 5-2).

-After all rafters are installed, layout the lattice tubes on the rafters with the seam side facing up. See Fig. 5-3 for lattice spacing

details. Similar to how you determined Distance A in Step 2, subtract one from the number of lattice tubes and multiply that by

the center to center spacing of the lattice. Subtract that from the length of the rafter and divide by two.

-The standard lattice spacing is 4 1/2" on center. If this is the case for your project, you might have received a short piece of

3" square tube. Simply placing this between two lattice tubes will give you the correct lattice spacing.

-Once a lattice tube is in the correct position, attach it to each rafter using #10 x 2" sheet metal screws (see Fig. 5-4).
