RACO 205RAC – Frequently Asked Questions
1) Will the RACO 205RAC fit a 4 inch square electrical box already in my ceiling?
Yes. The 205RAC is a 4 in. square cover sized for standard 4 in. square boxes, which is the most common box in existing commercial ceilings. The square profile lines up with the box opening, so it mounts to the box you already have rather than requiring you to pull and replace it.
2) Can I mount a smoke detector or exit sign to a 4 inch square box using the RACO 205RAC?
That is exactly what it is for. The 205RAC RETRO-RING cover is built to provide structural support for life safety fixtures, including smoke detectors, exit signs and emergency lighting, mounted to an existing 4 in. square box.
3) Is the RACO 205RAC old-work cover UL listed for inspection?
It is cULus Listed, which covers both US and Canadian listing requirements. That is the certification an inspector will look for on a life safety fixture support in a retrofit.
4) Do I have to open up the drywall to install the 205RAC RETRO-RING cover?
No. The RETRO-RING Series is an old-work configuration, meaning it installs into finished walls and ceilings without cutting into surrounding drywall or framing. That is the whole point of the design: you add fixture support without demolition or a full box replacement.
5) What is the difference between a standard 4 inch square box cover and the RACO 205RAC RETRO-RING?
A plain 4 in. square cover closes the box and gives you a device or fixture opening. The 205RAC goes further: it is engineered to carry the load of a life safety fixture on an existing box, in situations where direct structural attachment is not accessible. If you just need to blank off or trim a box, a standard flat or raised cover is the cheaper choice. If the fixture needs supported mounting in finished construction, the RETRO-RING is the one.
6) What part number do I order for the RACO 4 inch square life safety retrofit cover?
Order RACO 205RAC. It is a single configuration, square, 4 in., in the RETRO-RING Series, so there is no finish or size option to specify.
7) Can I use the RACO 205RAC on a residential remodel, or is it a commercial-only part?
Both. The 205RAC is specified for commercial and residential electrical renovation work, since 4 in. square boxes and retrofit smoke detector mounting show up in each. Property managers replacing detectors across occupied units can use the same cover they would spec in a commercial ceiling.
