Installation Process


Installing electrical box extenders is a straightforward task that DIY enthusiasts with basic electrical knowledge can complete. Remove the outlet or switch cover, attach the extender to the current box, and secure it in place using screws. Finally, reattach the cover and test the attachments.

Increasing Safety


On top of improving the safety of electrical equipment, electrical box extenders guarantee that your construction meets all building laws and requirements. Adequate space within electrical crates reduces the risk of overheating, short circuits, and electrical fires.

Waterproof and Weatherproof Options


Waterproof and weatherproof electrical box extenders can be utilized for outdoor electrical machinery or locations prone to moisture exposure. These specialized extenders give added defense against water ingress and environmental elements, safeguarding electrical fastenings in external settings.

Retrofitting Existing Fixtures


These extenders are helpful not only for new buildings but also for retrofitting existing units. If the electrical box is too shallow to fit supplementary wiring, placing an extender can resolve the issue without requiring extensive rewiring.
