Sleek Design That Hides Cables Well
Color: White, Size: 3FT(13A), Color: White, Size: 3FT(13A)
This flat plug extension was super easy to set up and works exactly as expected. We mounted it on drywall using anchors (not included), but that wasn’t an issue since we already had some. The flat plug design is great for tight spaces, and it really helped clean up our bedside area by keeping cables neatly hidden and organized. Definitely a practical and space saving solution!

Solves the problem of the ground location.
Color: White, Size: 5FT
In the master bath a lot of things need power. It really helps to be able to rotate the plug head to leave room for other devices.
