The Metacaulk Cover Guard is a one-piece, fire-rated gasket. It's specially designed to meet the '24-inch rule' for electrical boxes in rated walls. When heated, its intumescent material swells up to form a char, sealing gaps, stopping flames from spreading, and keeping heat away from unexposed areas. This guard is perfect when electrical boxes face opposite ways and are less than 24 inches apart horizontally. It also solves the problem for standard electrical boxes that break the 100 square inch rule. Key features include excellent fire protection, easy installation on cover plates, a space-saving design, sound control with an STC rating of 54, compliance with ASTM E814 (UL 1479) standards, and versatility for both metal and plastic cover plates with 1 and 2-hour fire ratings. Applications involve using it for specific electrical box setups and when the 100 square inch rule is violated. Product details show it comes in a case weighing 1.90 lbs with dimensions of 5.25' H x 4.75' L x 4.50' W, is black in color, from the Metacaulk Cover Guard brand, has a UPC of 021449662765, and an interleaved number of 10021449662762. Choosing this product means reliable fire protection, easy installation, cost - effectiveness, sound reduction, and compliance with standards.


Using the Metacaulk Cover Guard is a breeze. Just mount it on the inside of the cover plates at the same time you're installing them. This saves you time and labor. When installing, make sure the electrical boxes are set up as required in the product's applications section. For example, if the boxes face opposite directions and are less than 24 inches apart horizontally, this is the right place to use it. As for maintenance, there's not much to do. Just keep it in a dry place away from extreme heat. If you notice any damage to the intumescent material, it's time to replace it. Remember, this product is designed to keep your electrical installations safe and compliant with fire - rating standards, so use it correctly for the best results.
