Steel City GW 125 G – Frequently Asked Questions

1) What sizes does the Steel City GW gangable masonry box come in?
Two capacities: a 15 cubic inch box (MPN GW 125 G) and a 22 cubic inch box (MPN GW 235 G). Both are steel gangable masonry boxes, so pick by the volume you need for your conductor and device fill.
2) Can I gang Steel City GW masonry boxes together for a two or three gang device opening?
Yes, the GW is a gangable masonry box, meaning the sides come off so boxes can be joined side by side to build multi-gang openings in block or brick walls. Order one box per gang; they are sold each.
3) Should I use a masonry box or a regular gangable device box in a concrete block wall?
Use the masonry box. The GW is built for setting into block, brick, or poured concrete, where the box is buried in the wall and the plaster ring or device sits flush with the finished face. A standard nail-on or bracket device box is made for stud framing and has no place in masonry construction. If the wall is wood or steel stud, a standard steel device box is the right call instead.
4) Which GW box do I need for a single switch or receptacle with a few conductors?
For a single device with a modest conductor count the 15 cubic inch GW 125 G is the common choice. Step up to the 22 cubic inch GW 235 G when you have more conductors, a pigtail splice, or a larger device in the box, since box fill has to be calculated from the number and size of conductors, clamps, and devices.
5) What is the Steel City GW masonry box made of, and what does it look like once installed?
Steel construction with a silver finish. In a masonry wall the body is buried and only the device opening shows, so the finish matters for corrosion handling and identification more than appearance.
6) Where are Steel City GW masonry boxes made?
Canada. That is worth knowing for public and institutional jobs that carry country-of-origin reporting on electrical material submittals.
