For more security in high traffic zones, the Surface Impaler is designed with a glue zone at the center of the panel. This allows you to add a dab of adhesive to firmly hold the panel in place. This is also a good idea when installing Broadway panels in public places such as schools. Since the adhesive only makes contact with the impaler and the panel, you do not suffer the problem associated with foam panels that causes wall defacement due to the glue residue.
