Step 1: Install Pipe Cap on Vertical Pipes
Before installing Pipe Caps, verify that all
Vertical Pipes are level to one another.
Install one Pipe Cap on each Vertical Pipe.
The Pipe Caps have three or four set bolts
each to secure the Pipe Caps to the Vertical
Pipe. (See Figure 1-1)
A. Slip the Pipe Cap on top of the
Vertical Pipe and slide it down until
it rests/bottoms out on top of the
Vertical Pipe.
B. Rotate the Pipe Cap so that the long
dimension of the flange is aligned
in the E-W direction.
C. For now, finger-tighten the three or
four set bolts so that the Pipe Cap is
free to rotate as needed for Step 2.
Step 2: Install the Horizontal Tube
The Horizontal tubes are secured to the Pipe Caps using a Top Plate along with four
carriage bolts and flange nuts. The Tubes have been cut to length to match the spans
of the previously installed vertical pipes. The ends of the Tubes are butted to each
other on top of each Pipe Cap. (See Figure 2-1)
A. Lift and position the Horizontal
Tubes onto the Pipe Caps, creating
a butt joint centered (+/- 1") over
the Pipe Cap.
B. Install the Top Plate, securing it to
the Pipe Cap with four 1/2" x 6" or
7" Carriage Bolts and Flange Nuts.
Torque to 55-60 ft.-lbs.
C. Tighten the three or four set bolts
on each Pipe Cap. Torque to 32-34
ft.-lbs. for 3/8" hardware or 55-
60 ft.-lbs. for 1/2" hardware.
D. Repeat for all remaining Pipe
Caps.
