BASEBOARD NOTE
A customer-supplied baseboard and retaining board
are required
to attach the drop-down side curtains. The
baseboard is optional but recommended for a building
with a roll-up side. See the exploded view below.
The baseboard runs the length of the frame at ground
level. The retaining board secures the drop-down curtain
to the baseboard.
The baseboard and retaining board are
supplied by the customer.
Retaining boards are attached during the drop-down
curtain installation. The retaining board is not used when
the building is equipped with a roll-up curtain.

can be lowered a few inches to overlap the purlin
