Steel City 665-CI – Frequently Asked Questions
1) Will the Steel City 665-CI floor box fit in a shallow concrete pour?
Yes. The 665-CI recessed floor box has an overall height of 3-1/2 inches, which is what lets it go into shallow pours where a deeper box will not fit. Before the pour you get 2-1/2 inches of adjustment from the four leveling screws, so you can bring it to grade in the deck.
2) Can I still adjust the Steel City 665-CI after the concrete is poured?
You get 3/4 inch of after-pour adjustment from the self-leveling cover, so the box can be brought flush once carpet, tile, or wood goes down over the slab. That is the range you have to work with, so the pre-pour setting with the leveling screws still needs to be close.
3) How many devices can I put in a Steel City 665-CI floor box?
Up to four device panels in the one box, with 126 cubic inches of access area, which is enough room to dress workstation cabling rather than cram it. That is what makes it a single-box solution for a power-plus-data poke-through at a desk cluster.
4) Can I run both power and data into the Steel City 665-CI, and from which direction?
Feed-through is available from all four sides, so conduit can enter from any orientation and you can keep power and data/communications runs separate through the box. There are 28 knockouts total, sixteen at 1-1/4 inch and twelve at 3/4 inch, so you are not forced into one trade size.
5) Can the Steel City 665-CI floor box be mopped or wet cleaned?
Yes, it is rated suitable for wet cleaning, which matters in lobbies, classrooms, and hospitality floors that get mopped on a schedule. It is also suitable for hollow floor construction, not only poured slab.
6) Does the Steel City 665-CI cover work with a carpet opening?
No. The 665-CI is not configured with a carpet opening, so if your detail calls for a carpet-flange style cover you need a different cover arrangement. The cover here is rectangular, and the self-leveling design is what accommodates the floor covering thickness instead.
7) How much does the Steel City 665-CI weigh and how big a deck opening do I need?
Each 665-CI ships as a single unit weighing 27.52 lbs, with outer dimensions of 13.1 x 11.3 x 11.8 inches. Use those numbers when you block out the deck and when you plan handling, since it is a two-hand box on a ladder or a deck.
8) What exactly do I order to get this Steel City floor box?
Order by manufacturer part number 665-CI from Steel City. It is a single catalog number, a recessed service floor box, with no finish or size options to select.
