END WALL INSTALLATION (continued)
4. Secure the base tube between the legs of the end
rafter using an angle bracket and Tek screws.
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 double
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.
IMPORTANT: Actual number of band clamps may
differ from example shown. Consult end frame
diagrams in Quick Start section for details.
8. Select the tubing for the two vertical frame supports for
the sides of the double door. Each support includes:
• Square tubing (#102897 swaged end): For the
longer vertical frame members, shorter sections of
tube may need to be cut and added.
• 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 vertical section of the door frame tube.
10. Choose one 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 this assembled frame member, 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
frame tube. See the diagram that follows.
12. Select a square-to-round tube connect bracket and
attach the bracket to one end of the vertical frame
member. 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 vertical frame
member for the door.
14. With the square-to-round tube connect bracket
attached to the top of each vertical door frame tube,
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 vertical door frame members should be loosely
attached to the end rafter assembly.
