The Surface Mount Disc is a hard plastic disc with the hook side of a hook-and-loop fastener on the front. A 1/8-inch screw hole in the center of the disc lets you easily and securely install it to hard surfaces. The hook on the disc will connect with any standard loop tape. Great for RVs, boats and homes, the Surface Mount Disc Hook can be used to hold shades or blinds in place when pulled down or used in place of traditional hooks to hold curtain tiebacks. Disc diameter is 1-1/8 inches.
