Key Features and Benefits of This Octagon Box

The 26 cubic inch capacity gives room for wiring and connections behind a ceiling fixture. Built-in clamps help secure non-metallic cable without a separate connector, which saves installation time. The plastic body is also lightweight.

Where to Use the 20475 Octagon Box

This box is meant for interior ceilings, where it can support a light fixture, smoke detector, motion sensor, or other wiring device. It is not intended for exterior ceilings. Use it in wood-frame construction, and confirm that it suits your project type.

Installation and Compatibility Checks

Check the box capacity against the number and size of conductors and devices you plan to connect, as 26 cubic inches limits fill. Confirm the clamps suit your non-metallic cable. Dimensions and mounting details are not listed on the product page, so review the specification sheet.

Additional Buying Context

Check local electrical code requirements before choosing a non-metallic box. Certification and warranty details are not shown on the Lumenco page, so see the specification sheet and Lumenco's general manufacturer warranty page for more.
