Topaz Lighting 572MHDG – Frequently Asked Questions

1) Will the Topaz 572MHDG cover fit any conduit body, or only Type LR?
It is built for Rigid Type LR conduit bodies. The integral gasket seats against an LR body to make the raintight seal, and the cover is sized to LR openings in 3/4 inch, 1 inch and 2 inch trade sizes. If you are covering an LB, LL, T or C body, this is the wrong cover.
2) Can this conduit body cover be used outdoors in a wet location?
Yes. The cover has an integral gasket that makes a raintight seal when installed on a Rigid Type LR body, and the hot-dip galvanized malleable iron holds up to weather and moisture. It is listed for indoor and outdoor use, which covers exposed rooftop, exterior wall and yard raceway runs.
3) Do I need to buy a separate gasket and screws with the Topaz 572MHDG cover?
No. The gasket is integral to the cover and galvanized steel cover screws are included, so nothing else is needed to close up the LR body. Using galvanized screws keeps the whole assembly corrosion resistant instead of putting plain steel fasteners into a hot-dip galvanized cover.
4) Does this Topaz cover meet spec for a code-required commercial electrical job?
It is UL 514B listed, NEMA FB1 compliant, and meets Federal Specification A-A-50563. The hot-dip galvanized finish thickness conforms to ASTM A123/A123M. That set is what most commercial and government raceway specs call out for a rigid conduit body cover.
5) Can I replace a cracked or missing cover on an existing LR conduit body with this one?
That is one of its main uses. As long as the existing body is a Rigid Type LR in 3/4, 1 or 2 inch trade size, this malleable iron cover drops on with its own gasket and screws and restores the raintight seal. Check the body itself for corrosion while you have it open, since a pitted body will not seal against a new gasket.
6) What trade sizes does the Topaz MHDG malleable iron LR cover come in?
Three: 3/4 inch (572MHDG), 1 inch (573MHDG) and 2 inch (576MHDG). There is no 1-1/4, 1-1/2 or larger-than-2-inch option in this group, so match the trade size of the body already on the run.
7) Is hot-dip galvanized worth it over a standard zinc-plated conduit body cover?
On anything exposed, yes. Hot-dip galvanizing lays down a heavier coating than electroplated zinc, and Topaz's process conforms to ASTM A123/A123M for finish thickness, which is what specs reference for coastal, corrosive-atmosphere and outdoor work. For a dry indoor run inside a conditioned building, a zinc-plated cover does the same job for less coating.
8) Can I use this cover on IMC conduit bodies as well as rigid?
The cover is specified for Rigid/IMC systems, so an LR body on an intermediate metal conduit run takes the same cover as one on rigid. Trade size still has to match: 3/4, 1 or 2 inch.
9) How many Topaz MHDG conduit body covers come in a pack?
They are packed 100 to a carton. That works for a contractor stocking a truck or an MRO storeroom standardizing one cover across a facility, but it is worth knowing before you order a single replacement cover for one damaged LR body.
10) Why malleable iron instead of a stamped steel or aluminum conduit body cover?
Malleable iron takes impact without cracking, which matters on exposed industrial runs, loading docks and equipment yards where a cover gets hit. It also matches the material of standard rigid iron conduit bodies, so you are not mixing dissimilar metals at a gasketed joint in a wet location.
