FR101F Arlington Industries Non-Metallic Flange Box

Designed for new construction, Arlington’s non-metallic FR series device and fixture boxes have interchangeable backs and extension rings that allow one box to work with almost any exterior wall finish thickness. Get everything you need – and more, without buying extra pieces separately. That’s flexibility! Remove the back and re-install it on the opposite side of the box for the 5/8 inch depth (add extension ring for 7/8 inch).
