Installing the Stop Brackets
Small parts box (Figure 5).
1. Locate the two Stop Brackets from the small parts box (Figure 5).
2. Remove the two Thumb Screw Knobs from the front corner of the canvas.
3. Position the bracket so it looks like an upside down “L” facing in towards the
center of the canvas. Feed the two bolts through the holes in the bracket and screw
the two Thumb Screws back on (Figure 46). Tighten the thumb screws down by
using a 1/2” wrench on the backside of the hex bolt to prevent it from spinning.
4. Repeat steps 2 and 3 on the other corner to install the 2nd Stop Bracket
Tighten Hardware
With all the major components installed onto the frame, we can now go back and tighten all the hardware we intentionally
left loose.
1. Start by tightening the 10 Retainer Stud Locknuts (5 on each side) using a 7/16" Wrench (Figure 47).
2. Tighten the back Outer Link Assembly using a 1/2” Wrench on the hex heads inside the canvas and a 1/2" deep socket on
Lock Nuts outside the canvas (Figure 48).
3. Fully tighten all Thumb Screw Knobs.
