Mitten Mount Master Square



The J-BlockĀ® mounts provide multiple uses, including the ability to easily and attractively mount light fixtures and receptacles. These Mounting Blocks are the industry standard for mounting all exterior fixtures on any surface. Distinctive style and matching colors paired with durability and easy installation make these the mounting blocks of choice. These products conceal the cut edges of siding for a finished, professional look, while eliminating moisture and air infiltration. Made by Ply Gem, these Mounting Blocks are perfectly colour matched to all Mitten siding colors.
