FRAME CHECK
Before you attach the side curtains, inspect the frame for
sharp edges or fasteners that could damage the curtain or
kit components.
1. Verify that all frame members are properly secured.
2. Verify that all bolts and clamps are tight.
3. Recheck the frame assembly for sharp edges or
clamps and bolts that may interfere with the installation
of the curtain. File or tape sharp edges as needed.
4. Reposition clamps and bolts as needed and tape all
rafter pipe joints with duct tape to protect the curtain.
5. Verify that the main building frame is properly and
adequately anchored.
Do not attach the side curtains to an unanchored
frame.
6. Continue by installing the side curtains and
components.
INSTALL THE DROP-DOWN SIDES
If your building includes roll-up sides, go to and complete
the
"Install Roll-Up Sides"
procedure.
Do not continue
with these drop-down curtain steps.
Locate these parts to attach the pulleys and drop-down
curtain axle:
• 131S075 (1.315 swaged pipe for axle) and 131P0XX
(where XX represents the length needed to complete
the axle assembly). See side profile for pipe
identification if needed.
• 106734 band clamp
• 103496 gearbox and 103544 mounting plate
• 102717 double drive
• FA4482B Tek screws (for axle conduit)
• FAH009B (1/4" x 4" carriage bolts) and FALB01B (1/4"
nuts)—use with FAME50B flat washers on the nut side.
• FAH005B (1/4" x 2" hex head bolts)
• FALF15B (1/4" lock nut) and FAME50B (1/4" flat
washer)—used to secure the mounting plate.
Continue with the steps that follow to install the drop-down
curtain components.
