Box Seals

When noise becomes an issue, the instinctive response is often to build a thicker wall. After all, partitions create privacy, and seem like they should stop sound. In reality, sound travels readily through sound flanking paths (openings in the walls) like recessed outlet boxes. The Box Seal is a wall plate gasket that serves as an acoustic wall plate seal and fire prevention measure, effectively plugging these holes.

The Box Seal is available in multiple configurations, including all common NEMA configurations, and fits all major manufacturers’ wall plates.

The 1-gang Duplex Box Seal is UL-listed as a wall opening protective material for one-hour fire partitions, even back-to-back, when used with a metal wall plate.
