INSTALL POLY LATCH U-CHANNEL
The double poly latch U-Channel (#104211) is attached to
each side of the frame and runs from the front to the back
of the shelter. The position of this U-Channel identifies
the highest "open" position of the roll-up side panels. Tek
screws are used to secure the U-Channel to each rafter
and to secure the splice where two separate U-Channel
sections meet between two rafters.
The single poly latch U-Channel (#102197) is attached
to the top of each end rafter using Tek screws. This U-
Channel is used to secure the center portion of the main
cover that is not part of the roll-up sides. (This is the section
of the main cover that runs down the middle of the frame
at the top stretched between the two runs of double poly
latch U-Channel.) During installation, the single poly latch
U-Channel will bend with the curve of the end rafter as it is
attached.
Gather the parts:
• Aluminum single U-Channel (#102197): End Rafters
• Double poly latch Channel (#104211): Sides
• Tek screws (#FA4482B)
1. Measure the desired height (4'-6') to identify the top of
the roll-up side and mark the location on the end rafter.
2. Move to the other end of the frame and repeat Step 1.
3. Stretch a chalk line between the marks and snap to
mark the location of the double poly latch channel.
