Panels are all aluminum (size 28Vi" x 44 V2" each) covered with Velcro fabric. Objects of all shapes and sizes can be attached with a small piece of self-adhesive Velcro Hook Tape whose stiff hooks grip the invisible loops of the Velcro fabric. Objects can be attached and removed thousands of times without marring the surface. Standard set of four panels with five leg assemblies makes a display unit 10' wide and 6'/2' high. Height can be reduced to 4' for window or table display. Panels are reversible, covered with black Velcro on one side and either red or green Velcro on reverse.
