For installation into or onto hard surfaces, Rotator Rod now offers special adhesive adapters utilizing patented technology--allowing for permanent installation into/onto hard surfaces without drilling.. These adapters can be removed when desired without any residual damage to the surface. German engineered technology combines a high-performance, single component adhesive with a patented adapter, custom designed to fit the Rotator Rod, that provides a secure attachment--without drilling, without mess and without causing damage to hard surfaces. The bond is strong and permanent and in most cases removable without leaving a trace. The adapters will work on smooth and rough hard surfaces including: ceramic tile, natural stone (including marble and granite), glass, wood, steel, metal, concrete and brick, plastic and fiberglass.
