Feature: These types of fasteners have a modern, elegant and concise style. The RiseOm standoffs is designed to accommodate pictures, glass and signs indoors or outdoors, and can be used to create a three-dimensional signboard display without a frame. Very easy to install. Just install the plastic expansion tube on the wall and fix the positioning screws with screws. At the same time, there is no need to worry about damaging the product, because the contact surface between the screw and the product is protected by a rubber pad.
