Step 2: To attach the Mount Tube to the Mount Bracket, align the bottom hole at the base of the
Mount Tube to the arched slot at the bottom of the Mount Bracket right side flange.
Insert a 7.94 mm x 19.05 mm (5/16” X 3/4") UNC Carriage Bolt through the right flange and
wall of the Mount Tube. Secure the Carriage Bolt using a 7.94 mm (5/16”) UNC Serrated
Flange Nut inside the Mount Tube.
Repeat this procedure to attach the Mount Bracket left flange to the bottom hole at the base of
the Mount Tube.
Next, swing the Mount Tube up to align the top hole at the base of the Mount Tube with the
center hole in the side flange of the Mount Bracket. Pass a 7.94 mm x 63.5 mm (5/16” X 2 1/2")
UNC Hex Head Tap Bolt through the hole in the right side flange, the Mount Tube, and the left
side flange and secure using a 7.94 mm (5/16”) UNC Serrated Flange Nut (Figure 4-2).

Step 3: Remove the Adjustable Tri Mast Stays from the package and loosen all of the 7.94 mm
(5/16”) UNC joint hardware. Caution edges may be sharp; gloves are recommended.
Position the Tube Collar just below the bend in the Mount Tube (Figure 4-3). Attach the
adjustable stays to the collar as demonstrated in (Figure 4-3).
The adjustable Stays should be assembled so that the notch is visible on the left hand side of the
assembly. Place an adjustable Stay on each side of the Tube Collar flanges and align the holes.
