5. On the base tube surface facing the inside of the
greenhouse, install a short Tek screw at each joint and
then locate and mark the center of the base tube.
6. Consult the End frame diagram (Quick Start section)
and
mark the rough opening for the width of the door
assembly
.
7. Place the band clamps on the end rafter above the
door as shown below.
DO NOT TIGHTEN THE BOLTS
AT THIS TIME.
ATTENTION:
The frame shown below may differ from
the end wall frame. Consult the diagrams in the Quick
Start section to view the frame for this shelter.
8. Select the tubing for the two vertical frame supports for
the sides (jambs) of the door. Each support includes:
• One (1) long 99" section of square tubing (#102897
swaged end)
• One (1) short section of square tubing (if needed).
This is cut from a swaged end tube (#102897).
• One (1) square-to-round tube bracket (#104074)
9. Measure the distance
between the top of the base tube
and band clamp (Step 7)
to determine the length of the
first door jamb.
NOTE:
If the measured length is longer than 99", an
additional section of square tubing is required (see
Step 10). If the distance is 99" or shorter, skip to Step
11.
10. Choose one (1) square tube (#102897), insert the
swaged end of the long tube into the plain end of
another tube and tap with a hammer to properly seat
the tubes at the joint.
11. On the door jamb, mark the length determined in Step
9 (above) and
subtract the amount needed to account
for the square-to-round tube connect bracket
, which is
attached to the top of the door jamb. See the diagram
that follows.
12. Select a square-to-round tube connect bracket and
attach the bracket to one end of the door jamb. Use a
5/16" drill bit to drill a hole through the tube and attach
the bracket to the tube using a nut and carriage bolt.
13. Repeat Steps 9-12 for the remaining door jamb.
14. With the square-to-round tube connect bracket
attached to the top of each door jamb, use the bolt
in the band clamp to attach the bracket to the band
clamp. DO NOT TIGHTEN AT THIS TIME.
NOTE:
The heads of the bolts for each clamp are to the
outside (or front/back) of the greenhouse. At this point,
the two door jambs should be loosely attached to the
end rafter assembly.
