FloorBoss Signs consist of an A-frame made of durable, injection-molded plastic. This plastic is lightweight polypropylene with reinforced ribbing for extra strength. This frame also has an easy-grip handle on the top. You also get two thick plastic message panels with this self-standing frame. These panels printed with your “Adult Supervision Required” message fit into each side of the frame for a double-sided view. Panels can be permanently locked into place (with included rivets) or can be swapped out modularly. ConeBoss Signs, on the other hand, need a traffic or safety cone for mounting. Made of rigid, 3/16” thick, injection-molded plastic, Cone Signs for pools fit snuggly over most common sized traffic cones.
