Metacaulk Cover Guard Single Gang Switch

Metacaulk Cover Guard Single Gang Switch Fire-Rated Gasket Metacaulk Cover Guard Single Gang Switch is a fire-rated gasket designed for electrical boxes to meet fire safety requirements such as the "24-inch rule" in fire-rated assemblies. This product is used primarily by electrical distributors and switchgear suppliers to enhance fire protection in electrical installations. When exposed to heat, its intumescent material expands to form a char that seals openings, preventing flame spread and limiting heat transfer to unexposed areas. It is compatible with both metal and plastic cover plates and is suitable for retrofit applications in lighting solutions and wire and cable installations.
