The Cross Base with 1.5″ X 3″ Pin is a lightweight and low-profile base for Uprights up to 8′ in height. This cross base is ideal when you need a quick assembly and take down of your Pipe and Drape display. The base can be disassembled into flat pieces for storage. There are two different pin sizes available, a 3″ and a 6″. The pin size affects the height of the Pipe and Drape. The 6″ pin is used for Uprights 3′ to 8′ tall while the 3″ pin is designed for Uprights 3′ and shorter.
