RACO RACO125 – Frequently Asked Questions
1) Will the RACO 125 octagon box accept 1/2 in. EMT connectors?
Yes. The RACO 125 is a 4 in. drawn steel octagon box with nine 1/2 in. knockouts, so it takes standard 1/2 in. conduit connectors. It is built for conduit wiring systems, not cable-clamp cable runs, so you supply the connector for the raceway type you are running.
2) Does the RACO 125 come with a mounting bracket or do I need to fasten it myself?
No bracket. The 125 ships as a bare box, so you mount it directly to the surface or structure with your own fasteners, or support it off the conduit. If you need a box that nails or screws straight to a stud, look for a bracketed octagon box instead.
3) Is the RACO 125 UL Listed for commercial and institutional jobs?
Yes, the 125 octagon box is UL Listed, which is what an inspector and most institutional specs want to see on a steel outlet box. It is intended for conduit wiring systems in residential and commercial electrical work.
4) How deep is the RACO 125 octagon box, and is there enough room for several splices?
Depth is 1-1/2 in. on this 4 in. octagon. That is the mid-depth octagon size, enough interior space for typical splices and a ceiling fixture pigtail, but you still have to run the box fill calculation for the number and size of conductors you are putting in it.
5) Can I use the RACO 125 as a ceiling box for a light fixture?
It works as a standard 4 in. octagon junction or outlet box for splices and device mounting in conduit systems. Fixture support is a separate matter: the box ships with no bracket, so use it where the box itself is securely mounted and the fixture weight is supported as the fixture and code require. For a paddle fan you need a box and support assembly specifically listed for fan support.
6) Does the RACO 125 include a cover or plaster ring?
The 125 is the box only. Covers, blank plates, and plaster or mud rings for a 4 in. octagon are ordered separately. Pick the ring depth to match your finished wall or ceiling thickness so the device or fixture canopy sits flush.
7) Is a drawn steel box different from a welded one, and does it matter for my install?
Drawn means the 125 is formed from a single piece of steel rather than assembled from panels and welded at the corners. For the installer the practical difference is a seamless body with no weld seams at the corners. Either type is used in conduit rough-in; drawn boxes are the common choice in the standard 4 in. octagon size.
8) What is the RACO part number for the 4 in. octagon box with 1-1/2 in. depth?
Order it as RACO 125. That is the 4 in. drawn steel octagon, 1-1/2 in. deep, no bracket, nine 1/2 in. knockouts, UL Listed.
