Metacaulk Cover Guard is a one - piece fire - rated gasket that meets the '24 - inch rule' for electrical boxes. When it gets hot, its intumescent material swells up to form a char, sealing the opening. This stops flames from spreading and cuts down on heat transfer. Key Features: Fire protection and safety are top - notch as the intumescent material expands under heat to block flames and reduce heat. Installation is a breeze as it mounts inside the cover plate during setup, offering fire protection without using up space in the electrical box. It's cost - effective and efficient, a labor - saving option compared to putty pads for regular use. It also cuts down on sound with an STC rating of 54. And it's been tested and approved, meeting ASTM E814 (UL 1479) standards. Product Details: The case weighs 1.58 lbs, measures 5.25' H x 4.75' L x 4.50' W, and the gaskets are black. The brand is Metacaulk Cover Guard. Application: Use it when electrical boxes in rated walls face opposite directions with less than 24 inches of horizontal space between them. It can also be used for standard electrical boxes when the 100 - square - inch rule is broken.
