The Octagon Vapor Barrier with Tang is designed for use with steel octagon electrical boxes up to 2.5" deep. It helps create a protective barrier around the electrical box during ceiling or wall installations where vapor barrier protection is required.

The clear octagon design allows the box position to remain visible during installation, while the tangs help secure the vapor barrier in place with compatible steel octagon boxes. This product is commonly used in residential, renovation, and contractor electrical projects where air sealing and vapor control around electrical boxes are important.

This is a practical option for electricians, builders, and contractors working on ceiling boxes, lighting rough-ins, junction boxes, and other approved octagon box applications.

Always confirm compatibility with the box size, installation method, and local electrical code before installation.
