MetaCaulk Electrical Outlet Cover Guards

Metacaulk Cover-Guards are single component fire-rated gaskets for use in electrical outlet boxes on fire-rated walls.  Cover-Guards are the quick and easy way to comply with the "24 Inch Rule".  Cover-Guards install easily and fit right behind metal or plastic outlet cover plates.  These electrical box inserts come in both standard and decor style in both single and double gang outlet covers and double and single switch covers.

How To Install:
Metacaulk Cover-Guards fit under the cover plate and do not take up volume in the electrical box. Cover-Guards are a labor saving replacement for putty pads in normal applications.  These electrical box inserts are acoustically tested to maintain an STC 54 rating. Tested in a UL 411 wall assembly/section to ASTM E90.

How They Work:
When exposed to heat, Metacaulk Cover-Guards expand (intumescent) forming a hard char that seals off the opening.  This expansion prevents the spread of smoke and flames along with minimizing the temperature rise on the unexposed wall surface.
