Refer to the installation drawing for dimension/details on upper support tubes. Start upper support tube assembly by inserting the swaged
end of first tube completely into the plain end of the second tube. Drill two (2) 13/64” dia. holes and secure the connection with two (2)
pop rivets. See Fig. C. Repeat the above steps for the other connections. After assembly, simply slide the end of the assembled support
tube into the upper curtain panel pocket. To facilitate the installation, slip the curtain support hanger assemblies around the upper support
as the tube slides past each upper pocket cutout. See cutout detail on page 7. If necessary, cut the swaged end of the tube assembly per the
installation drawing, after the upper support tube assembly is installed in the curtain
The lower support tube assembly can be installed in the curtain lower pocket before or after the curtain is suspended. Installing the support
tube assembly before the curtain is raised will increase the effort required to raise the curtain to the support structure. For this reason, if
space allows, it is advised that the lower support tube be installed after the curtain is suspended.
The lower support tube is assembled in the same manner as the upper support tube, with the exception of the weighted end section. The
weighted end section must be positioned at the
motor end for torque arm installations, and opposite end of the motor for wall guide
installations. In addition, the weighted section must not be altered. It must remain a full uncut section if the length of curtain allows it.
After assembly, simply slide the end of the assembled support tube (with weighted end positioned properly) into the lower curtain panel
pocket. If necessary, cut the end of the tube (without weight) even with end of the curtain. Secure the tube to the lower pocket at each end
with self drilling, self tapping screws. See pocket detail below.

8. TORQUE DRIVE INSTALLATION
The torque drive installation is divided in two sections due to the difference in installation procedures associated with each counter-torque
method. First, it is necessary to determine which type of counter-torque system is being utilized, either wall guide type or torque arm type.
Refer to installation drawing and illustrations below for proper identification of the system being used for the curtain installation.
