16. Using a level (or other means), verify that one jamb is
plumb and tighten the band clamp bolt to lock the first
door jamb in place.
17. Measure the width of the rough door opening between
the marks made in Step 15, and tighten the bracket for
the remaining door jamb.
18. Verify that both door jambs are plumb and recheck the
width of the rough door opening at the top and bottom.
Adjust if needed.
19. Choose one 96" square tube for the only horizontal
frame member (header) of the end wall framing used at
the top of the rough door opening.
NOTE:
The 96" length of the tubing is 3/4" shorter than
the actual rough opening of the door. The QH1330
angle brackets used to secure the tubing to the door
jambs are designed to adjust for this difference.
20. Using two (2) QH1330 angle brackets, attach the
header tube to the end wall between the door jambs as
shown.
21. Select the metal tubing (104779) for the three (3) short,
end wall supports (positioned between the top door
frame and the chord of the end wall) cut to the proper
length, and attach using the QH1330 angled brackets.
• One (1) long section of square tubing (plain end)
#104779
• One (1) short section of square tubing (plain end)
cut from standard 96" length
• One (1) square tube connector to connect the two
pipes: 104628
• One (1) 104624 square tube fitting to attach the
support to the bottom frame member of the end
wall assembly.
• One (1) 104074 square to round tube connector to
attach the tubing to the band clamp on the bottom
chord.
END WALL INSTALLATION (continued)
22. Use the End Wall Diagram to determine the number
of remaining vertical end wall supports and place one
band clamp (QH1402) on the chord of the end rafter
for each of the remaining vertical supports. Use the
diagram for the location of these clamps.
23. Begin at the center of one door jamb and measure and
mark (on the base rail) the locations of the remaining
vertical end wall supports. Use the End Wall Diagram
for the on-center locations.
24. Choose the parts for each remaining vertical support
for the end wall framing. Each vertical support consists
of the following parts:
Bottom Chord
QH1330
QH1330
Top of Door Frame
QH1330
104779
Chord
Header Tube
25. Use the steps presented earlier in these instructions to
measure and cut each short section of square tubing
for the remaining vertical frame members.
ATTENTION:
Remember to subtract 1-3/4" to account
for the 104074 square to round tube bracket that will be
attached to the top of each remaining frame members.
26. Once the short length is cut, join the two sections using
Tek screws (FA4484) and the 104628 square tube
connector. (See End Wall Diagram and Step 28.)
