EZ23SN-RG is a 1-gang, new work, vapor-proof EZ Box. It is an energy efficient electrical box for walls subject to unwanted air-flow. It eliminates air leaks with a solid drywall flange covered with a foam gasket and additional foam gaskets over 4 self-clamping cable entry clamps. These foam gaskets create a vapor-tight seal preventing air from flowing through the box. The 23 cubic inch EZ Box is the largest 1-gang box in the industry. EZ23SN-RG also feature enhanced angled nails for EZ secure installation.
