Carlon Single or Multiple Box Extender

Carlon Single or Multiple Box Extender

The B1MGEXT2 Carlon Box Extender is a non-metallic electrical box extension designed to bring recessed outlet and switch boxes flush with the finished wall surface after remodeling or wall finishing. Made from durable PVC, this extender is gangable, allowing it to be used on single or multiple-gang electrical boxes. It installs easily between the existing electrical box and the device, helping maintain proper spacing and compliance with electrical codes—because outlets should sit neatly in the wall, not hiding behind it.
