BASEBOARDS AND RIBBON BOARDS
The drop-down curtain requires a ribbon board to secure its
upper section and a baseboard to secure its lower section.
The materials for these components are not included and
are
supplied by the customer
.
The example
shows the required
ribbon board and
baseboard as
attached to the
frame.
Ribbon Board
Baseboard
A customer-supplied baseboard and retaining board are
also required to attach the curtain's lower edge. See the
exploded view that follows.
The baseboard runs the length of the frame at ground level.
The retaining board secures the curtain to the baseboard.
The baseboard and retaining board are supplied by the
customer.
Fasteners (1/4" x 4" carriage bolts and FA4652 wood
screws) are included. Depending on board width, use 2
carriage bolts per rafter connection for the baseboard and
ribbon board. Evenly space the wood screws at 24".
ATTENTION:
Consult the Main Cover Details diagram in
the Quick Start section of this manual to determine where
to install the ribbon board.
The ribbon board consists of two runs of material; the first
is a 2" x 4" or 2" x 6" board attached to the building frame
and the second is a 1" x 4" board attached to the first
board. These boards, when assembled properly, provide
a channel that secures the curtain when it is in the up or
closed position. Boards are secured to the frame using the
supplied 1/4" x 4" carriage bolts and to each other using the
FA4652 supplied fasteners.
