FAQ:

Q: How do you attach a box extender to an electrical panel?

A: Gently pull the device out of the electrical box. Slip the box extender over the device and slide it into the electrical box. The fit should be tight. Often, you can slide the extender over the switch or receptacle without even disconnecting the circuit wires.

Q: How do I choose the best box extender for my box?

A: Box extenders are available in several sizes and shapes to match different box sizes and different depth needs. Make sure to choose one that matches the outer dimensions of your electrical box, and one with a depth that closely matches the gap between the face of the wall and the front of the recessed electrical box.

Q: Are box extenders necessary for remodeling?

A: Box Extenders Are Helpful For Remodeling Projects. The electrical code requires that all electrical boxes, including those holding outlets, switches, or light fixtures, must be installed so that the front face is flush with the wall surface. This is to ensure that the box is sealed and the wires inside properly protected.

Q: What does it mean to extend a box?

A: When installed over an existing box, they extend the box so it is flush with the front face of the wall, thereby creating a code-approved enclosure for the wire connections inside. Box extenders are available in several sizes and shapes to match different box sizes and different depth needs.
