a) Roll up doors are not guaranteed to roll up completely if there is 1’ (foot) of space between the roll up door height and the leg height of the building. We strongly encourage the customer to have at a minimum, 2’ (feet) of difference between the leg height and the height of the roll up door. This is to ensure that the roll up door opens completely. b) Dealer and Seller are not responsible for any malfunctions with roll up doors if Buyer chooses to order a building with 1’ (foot) of space difference between the roll up door height and leg height of their building. c) Oversized and custom roll up doors must be paid for up front and are included in the deposit amount. Please note orders with oversized and custom roll up doors may experience extended lead times as these doors will need to be ordered.
