3-1/2 in. Clamp Back Spacers, Malleable Iron

These clamp back spacers are used in wet and dry locations in conjunction with malleable rigid conduit straps to create space between the 3-1/2 in conduit and mounting surface. These clamp back spacers can prevent the buildup of snow and rain between the conduit and mounting surface when used for outdoor applications. Garvin Industries' clamp back spacers have a zinc plated malleable iron construction to ensure durability, mechanical and corrosion protection. Their elongated bolt holes make alignment with the straps easy and quick. They also position pipes for insertion in boxes or enclosures.
