RACO 978 – Frequently Asked Questions

1) Is the RACO 978 support sized for 1-7/8 in. rigid conduit?
Yes. The 978 is a 1-7/8 in. trade size far side support built for rigid conduit box mounting. If your run is a different trade size or you are working in EMT or flex rather than rigid, this is not the support to order.
2) What is the difference between the RACO 978 far side support and the Mulberry 40490T08 box support bracket?
Material and intent. The RACO 978 is a molded plastic far side support sized for 1-7/8 in. rigid conduit, used to secure electrical boxes on the far side of a framing member. The Mulberry 40490T08 is a steel switch box support bracket. If weight and corrosion resistance matter on the run, the plastic 978 is the one; if you want steel in the opening, the Mulberry bracket is the steel equivalent.
3) What is a far side support used for in an electrical box install?
A far side support like the RACO 978 attaches on the far side of a framing member to stabilize an electrical box so it stays put while the conduit run is made up. It is the piece that keeps the box from rocking or pulling out of position once the wiring is pulled, and it is used in new construction and in remodel work where the box has to be held against an existing stud or joist.
4) Is the RACO 978 box support metal or plastic, and will it corrode in a damp location?
Molded plastic, not steel. That means it will not rust or corrode the way a steel bracket can in damp framing cavities, and it weighs less to handle on a lift or in an overhead cavity. The tradeoff is that plastic is not a load-bearing metal bracket, so it is meant for supporting the box on the framing member, not for carrying conduit weight on its own.
5) I need a steel box support instead of plastic - what should I order?
Order the Mulberry 40490T08, a steel switch box support bracket. The RACO 978 covering 1-7/8 in. rigid conduit is molded plastic, so where a job calls for a steel support the Mulberry bracket is the substitute to specify.
6) Can a switch box support bracket be used in place of the RACO 978 far side support?
Not interchangeably without checking the opening. The RACO 978 is a far side support built for 1-7/8 in. rigid conduit installations, attaching on the far side of a framing member to stabilize the box. The Mulberry 40490T08 is a switch box support bracket in steel, which is a different mounting approach. Confirm which support method your box and framing call for before swapping one for the other.
7) What is the RACO part number and MPN for this plastic far side support?
It is RACO 978, and the manufacturer part number is also 978. That is the only model in the family, so there are no size or finish suffixes to specify when you order.
8) Where can I get the RACO 978 spec sheet for a submittal package?
RACO publishes a spec sheet for the 978 far side support at https://hubbellcdn.com/specsheet/RACO-978-SPEC-EN.pdf. That is the document to drop into a submittal or an RFI when an engineer asks for manufacturer data on the box support.
