The Box Seal is a wall plate gasket that serves as an acoustic wall plate seal and fire prevention measure, effectively plugging spaces around wall outlets.
The STC Hi-Sabin Panel controls reverberant noise due to exposed ceilings, and offers more savings than other types of sound absorption panels.
The STC Acoustic Sleeper helps to prevent impact noise from reaching floors below.
The STC Mullion Seal closes the gap between a window and wall partition to stop sound from traveling trough these spaces.

The Box Seal has many benefits over products like sealants and putty pads, including:
To put the Box Seal’s effects into context, you can imagine a typical hotel room, which usually shares a wall with an adjacent room and has five recessed outlets on each side. Most hotel chains’ standards require a minimum STC-50 partition. However, with untreated outlets, the effective performance drops to STC-42.
Using a higher STC wall won’t fix the problem, as sound will still pass through the openings created by the outlet.
But simply installing Box Seal increases the performance of the wall by seven decibels.
Increased performance by seven decibels in a hotel with five outlets.
The Box Seal fits between the outlet box and the wall plate.
To install, simply remove the wall plate, fit the seal around the device and reinstall the wall plate.

Yes. The Box Seal spans the wall opening just like the wall plate so that it occupies no space inside the electrical box. Specifically, the requirements of Section 314.16 are unaffected by use of the Box Seal.

Yes, for fire-rated partitions up to 1-hour for the most common 1-gang duplex configuration. The Box Seal has been tested per UL 1479 and is listed in the Underwriters Laboratories Fire Resistance Directory as a wall opening protective device. Use with a metal wall plate when outlets on opposite sides of a fire-rated partition are less than 24-inches apart.
