The WindMaster® 5012SSAL takes up only 1-cubic foot of storage space and is designed for use with roll-up signs. Roll-up signs attach to the 5012SS with a screw-lock sign bracket (included). Simply slide the vertical cross brace into the bracket channel and secure the sign face by turning the screw handle until the cross-brace fits tightly against the pressure plate. The 5012SSAL features a single spring base design and adjustable, telescoping legs with kick-release buttons.
