Steel City 809 – Frequently Asked Questions
1) What does the Steel City 809 extension ring actually do on an existing outlet box?
The Steel City 809 is a multi-gang extension ring, model 809. It mounts to the front of an existing steel box to add depth and internal volume rather than replacing the box. It adds 46.5 cubic inches of usable space, which is what you need when the original box is crowded with conductors, splices and device yokes, or when a remodel has pushed the box face back behind new drywall or tile.
2) How many gangs does the 4-9/16 x 19-9/16 inch Steel City extension ring cover?
The ring measures 4-9/16 inches by 19-9/16 inches, so it spans a long multi-gang run rather than a single or two-gang box. Match it to the face dimensions of the ganged steel box already in the wall: the ring has to land on the box flanges on all sides, so measure the existing assembly before ordering rather than counting devices.
3) Does this Steel City extension ring come with knockouts for conduit?
No. The 809 ring ships with zero knockouts. Any conduit or cable entries have to come through the existing box behind it, or be punched in the field. If you need factory knockouts on the extension itself for added raceway, this is the wrong part for that job.
4) Will a steel extension ring work with a plastic or nonmetallic box?
No. This is a steel ring, built to sit on a steel box and maintain the metallic enclosure and its bonding path. Nonmetallic boxes use their own matching nonmetallic extensions. If the box in the wall is plastic, buy a nonmetallic extension instead of this one.
5) Does the added volume of an extension ring count toward box fill calculations?
Yes. The 46.5 cubic inches the 809 ring adds is counted along with the volume of the box it is mounted to when you work out conductor fill, which is the usual reason contractors add a ring to an overstuffed ganged box rather than opening the wall to swap it.
6) What finish is the Steel City 809 ring and will it match the other boxes in the building?
Silver, the standard plated steel look used across common steel electrical enclosures, so it blends with the boxes and mud rings already in a typical panel or device run. It is made in the United States, which matters if your job carries a domestic-content requirement.
7) Is the Steel City 809 extension ring sold individually or by the box?
It is sold each, so one ring per unit ordered. Quantity up for multi-device runs where every ganged box needs the same depth added.
