Metacaulk® Cover Guard™ is a single-component fire-rated gasket for use with electrical boxes when addressing the “24-inch rule.” It is mounted on the inside of the cover plate and installed simultaneously as the cover plate, covering the opening and providing the necessary fire protection.

When exposed to heat, Cover Guard’s™ highly intumescent nature causes it to expand, forming a char that will seal off the opening, prevent the spread of flames, and limit the temperature rise on the unexposed surfaces.

Cover Guard™ is applied by hand. It does not take up volume in the electric box and is a labor-saving replacement for putty pads in typical applications.
