Steel City GW335G-10R – Frequently Asked Questions

1) How deep is the Steel City GW335G masonry box, and how much volume does it give me?
The GW335G is a 3-1/2 inch deep masonry box with 71 cubic inches of volume. That depth and volume are what let you land several conductors and devices in a block wall without fighting for splice room.
2) What size conduit knockouts does the GW335G masonry box have, and how many?
It comes with 1/2 inch and 3/4 inch knockouts, 26 of them in total across the box. That gives you plenty of choice on which face and which side you feed from once the box is set in the block course.
3) Can I gang the Steel City GW335G to get a two or three gang opening in a block wall?
Yes, the GW335G is a gangable masonry box. The side plates come off so you can join boxes together for multi-gang device openings in masonry. Boxes are sold individually, so order one per gang you need.
4) Is a masonry box like the GW335G the right choice, or should I use a standard steel device box?
Use a masonry box when the box is being set into concrete block or poured concrete. The GW335G is built to sit inside the block cell with the device face flush at the wall surface, and its 3-1/2 inch depth is sized to the block. A standard nail-on or bracket device box is for stud framing and drywall and has no place in a block wall.
5) What is the manufacturer part number for the Steel City 3-1/2 inch gangable masonry box?
The Steel City part number is GW 335 G. It also runs as GW335G-10R in the 3-1/2 inch deep, 1/2 and 3/4 inch knockout configuration. Both carry the same 71 cubic inch volume.
6) What is the GW335G masonry box made of, and will it hold up in a block wall?
Steel construction with a silver finish. Steel is what you want in masonry work, since the box gets grouted in and has to take the abuse of the trowel and the block course without deforming.
7) Am I ordering the GW335G by the box or by the case?
The GW335G is sold each, one box per unit. If you are laying out a wall with multi-gang device locations, count every gang separately when you build the order.
8) Where is the Steel City GW335G masonry box manufactured?
It is made in Canada. That matters on public and institutional jobs where country of origin has to be documented in the submittal package.
