RACO RACO678 – Frequently Asked Questions
1) Will the RACO 678 handy box mount to metal studs, or is it wood stud only?
Both. The 678 ships with a TS bracket rated for mounting to metal or wood studs, so the same box covers steel stud commercial partitions and wood framed walls without a separate bracket or mounting strap.
2) How deep is the RACO 678 handy box, and is there room for a device plus conduit conductors?
The body is 2-1/8 in. deep (2.125 in.) behind a 4 in. x 2 in. handy box opening. That is the deep handy box size rather than the shallow 1-1/2 in. version, which is what gives you working room for a switch or receptacle plus the conductors coming in from conduit.
3) How many knockouts does the RACO 678 have and what size conduit do they take?
Eight 1/2 in. knockouts, spread for entry from multiple directions. Half inch KOs accept 1/2 in. trade size EMT or flex connectors, which is what most branch circuit switch and receptacle runs use.
4) Does a cover come with the RACO 678 handy box?
The 678 is the box and TS bracket only. A 4 in. x 2 in. handy box cover (blank, single toggle, or single receptacle, depending on what you are installing) is a separate item, as are your connectors and the device itself.
5) Can I use the RACO 678 for a flush mounted device in a finished drywall wall?
It is sized and bracketed for surface-mounted switch and receptacle work and for stud-mounted rough-in with the TS bracket. A handy box like this is typically used with a raised handy box cover rather than a flush device ring, so for a flush trim in drywall most electricians go to a standard 4 in. square box with a plaster ring instead.
6) Is the RACO 678 a drawn box or a welded box?
Welded. The 678 is a welded steel handy box, with seams joined rather than formed from a single drawn shell. Welded construction is the one spec inspectors and electricians look at when a box has to hold up to conduit torque during rough-in.
7) What part number do I order for the RACO welded handy box with the TS stud bracket?
Order RACO 678. That is the manufacturer part number for the 4 in. x 2 in. welded steel handy box, 2-1/8 in. deep, eight 1/2 in. KOs, with the TS bracket.
