Display your larger aluminum signs with the 12" cross piece sign to sign mounting bracket. This bracket fits over the top of an existing sign, but it is larger than other brackets of its kind, so it is suitable for medium and larger signs, whether directional or otherwise. The 90 degree cross piece is perfect for mounting industry or larger directional signage. It has screw holes for super simple installation on both ends and simply mounts to each sign. The 12" L mounting bracket is made of sturdy aluminum and fits standard street signs.
