Allied Moulded SB-CB – Frequently Asked Questions

1) Is the Allied Moulded SB-CB rated to support a ceiling light fixture, or is it just a wiring box?
The SB-CB Sliderbox is a dedicated ceiling fixture support box, not just a junction box. It is built to give a ceiling-mounted lighting fixture or similar ceiling device its mounting point during rough-in. If all you need is a wire splice point, a standard non-metallic ceiling box will do; if the fixture hangs from the box, this is the type you want.
2) How big is the Allied Moulded SB-CB box and how much wire volume does it give me?
Measures 4 x 2-3/4 inches with 25 cubic inches of interior volume. That capacity covers the conductors, grounds and connections typical of a ceiling fixture drop, and the compact footprint is sized to go in between ceiling framing and drywall.
3) Can I use a non-metallic box like the SB-CB instead of a steel ceiling pan?
Yes, that is the point of it. The SB-CB is polycarbonate, so it does not corrode and weighs less than a steel support box, while still serving as the fixture mounting point. Electricians running non-metallic cable often prefer it because there is no metal box to bond.
4) Is the Sliderbox SB-CB for new construction only, or can I use it on a remodel?
Both. The Sliderbox design is meant to be positioned and adjusted during rough-in on new construction, and it is also used on remodel and retrofit fixture support work. Residential and light commercial ceiling wiring are the typical applications.
5) Will a 25 cubic inch ceiling box be enough if I'm feeding through and looping other lights?
25 cubic inches is the working number to do your box fill against. It handles a fixture drop plus the conductors and connections normally landed in a ceiling fixture box, but if you are splicing several circuits through the same location you should run the fill calculation for your conductor count and step up to a larger box if it exceeds the volume.
6) What part number do I order for the Allied Moulded ceiling support Sliderbox?
Order Allied Moulded SB-CB. It is a single configuration, 4 x 2-3/4 inch polycarbonate ceiling fixture support box, so there are no finish or size options to specify.
