Steel City SBEX – Frequently Asked Questions

1) What does a Steel City SBEX extension ring do, and when do I need one?
The SBEX is a steel extension ring that bolts onto an existing electrical box to add depth. You reach for one when the device won't sit flush, the box is buried behind added drywall or tile, or the conductors and connectors already in the box leave no room to fold the device back in. It adds 3.5 cubic inches of usable volume, which is what matters when you're counting box fill on a crowded junction or device box.
2) Does the SBEX extension ring count toward box fill calculations?
It does, and that's most of the reason to use one. The SBEX adds 3.5 cubic inches to the total volume of the box, which you add to the box's own marked capacity when working out conductor fill for the devices and splices inside.
3) I'm remodeling and the outlets are now recessed behind new tile. Is an extension ring the right fix or do I replace the box?
An extension ring is the right fix and it's far less work. Pulling and resetting a box in a finished wall means opening the surface again; the SBEX just fastens to the existing box and brings the device face forward 7/8 of an inch. That's the retrofit case this ring exists for, on residential and commercial work alike. Replace the box only when you need more than the depth, for example a larger gang count.
4) How much depth does the SBEX ring add to an electrical box?
Seven eighths of an inch. That's the depth dimension on the 2 x 3 x 7/8 inch ring, so a device box sitting 7/8 inch behind a finished wall surface comes back out flush with one ring. Where the drywall or tile added more than that, you're stacking or moving to a deeper extension.
5) Is the Steel City SBEX steel or plastic, and does that matter for grounding?
Steel, with a silver finish. A steel ring keeps the metallic path continuous through the extension when it's fastened to a metal box, which is what an electrician wants on a metal raceway system. A plastic or PVC extension breaks that and forces you to rely on the equipment grounding conductor alone.
6) How is the Steel City SBEX sold, one at a time or by the box?
Each. The selling unit on the SBEX is a single ring, so you can order the exact count for the job rather than a carton. Model number is SBEX.
