Metacaulk Cover Guard is a 1-piece fire-rated gasket designed to meet the “24-inch rule” in electrical boxes.
When exposed to heat, its intumescent material expands to form a char, sealing the opening to prevent flame spread and limit heat transfer.
Key Features:
Fire Protection & Safety – Intumescent material expands under heat to block flames and reduce heat transfer.
Seamless Installation – Mounted inside the cover plate and installed simultaneously, providing necessary fire protection without taking up volume in the electrical box.
Cost-Effective & Efficient – A labor-saving alternative to putty pads for standard applications.
Sound Reduction – STC rating of 54 for added acoustic insulation.
Tested & Approved – Complies with ASTM E814 (UL 1479).
