Product Description

The 3M 7000148879 is a metal deck adaptor designed for use with 3-inch 3M Fire Barrier Cast-In Devices. It allows the cast-in device to be properly seated and installed on fluted metal deck construction, which is a common structural configuration in commercial and multi-story buildings. Installation requires a minimum concrete topping of 2.5 inches over the fluted deck.
