Rated to hold up to 10-pounds on smooth glass surfaces like windows, glass storm doors, mirrors and tile, the Giant Suction Wreath Holder features Adams signature light-diffusing rings and easy-removal tab. The light-diffusing rings prevent focused light from damaging surfaces. The extra-large hook and powerful suction cup holds wreaths or other decorations without wire or string. Great for most indoor and outdoor applications. Not recommended for wood, non-glass or rough surfaces.
