The STND-1500 is a medium size, non-penetrating roof mount with multiple applications. The mount is great for antennas and small MW’s. Perforated rubber mats (PRM) are recommended for extra grip and to prevent any damage to the roof surface. The mount is simple to install and can be modified by the installer. It can fit any pipe from 2 7/8” (73mm) to 4 1/2” (114mm).
