Using 1/4” x 1 1/2” self tapping screws mount
the Plastic Standoffs 2” below the drip edge and
right up against the corner brace as shown on

STEP 11 - 1” SQUARE TUBE
11.1 Insert the 1” 14 ga Square Tube into the tarp sleeve on the opposite side of the stiffening patch (see pg. 11,
Step 13 for a picture of the stiffening patch).
11.2 Center the 1” Square Tube inside the sleeve. This should leave around 2” of the tube sticking out of the
sleeve on each side as shown above.
11.3 Use a 1/4” drill bit to drill a hole through the Canvas Tarp and one wall of the 1” Square Tube. The hole
should be around 3/4” from the edge of the tarp.
11.4 Use a hammer to install a 1/4” Drive Rivet.
11.5 Repeat Steps 11.3 & 11.4 at the same location on the other end of the Square Tube.
-NOTE: Be sure the Tarp is pulled tight over the Square Tube in between the Rivets.
