Airtight cover for wiring

Abstract

This product relates to an airtight wiring cover for preventing airflow at the installation locations of wiring devices such as switches, outlets, and modular jacks for LAN cables on walls within a building. As illustrated in the reference diagram of its use, when an outlet is installed in a wiring box located on the back side of a wall material, this product is used to prevent airflow between the front and back of the wall material at the outlet's installation location, thereby maintaining the airtightness of the room.
