Topaz Lighting WRB1550B – Frequently Asked Questions

1) How many conduit entries does the Topaz WRB-1575 weatherproof box have, and what size?
Five 1/2 inch knockouts on a 4 inch round body. That gives you multiple entry points for feeding conduit in and out, so the same box works as a straight-through junction, a corner pull, or a single-entry fixture box. All the openings are 1/2 inch trade size, so plan on 1/2 inch fittings or reducers if you are running a different size.
2) What color options does the Topaz WRB weatherproof round box come in?
Three: aluminum (WRB1575), bronze (WRB1550B), and white (WRB1550W). Pick the one that disappears against the wall you are mounting to. Bronze is the usual choice on brick and dark trim, white on stucco and vinyl siding, plain aluminum where the box sits behind a fixture canopy and nobody sees it.
3) Is this Topaz round box aluminum or plastic, and will it hold up outdoors near salt air or a pool?
It's aluminum, not PVC. Aluminum is the reason this one gets specified for exterior work - it resists corrosion in wet and coastal conditions and won't get brittle in UV the way some plastics do. Topaz lists pool and landscape lighting among its typical uses. Bond it like any metallic enclosure.
4) Can I mount an outdoor light fixture or a receptacle cover on the Topaz WRB-1575?
Yes - it's a 4 inch round weatherproof box intended for exterior fixture mounting, outlet and switch mounting, and plain junction use. Covers and lampholder plates are ordered separately; the box itself is the enclosure and knockouts only.
5) Do the knockouts need to be sealed if I only use some of them?
Any knockout you open and don't fill has to be closed off, and any you leave intact stays intact. With five 1/2 inch knockouts you'll usually only punch one or two, so order 1/2 inch closure plugs or sealing washers along with your fittings to keep the enclosure weathertight.
6) Is the Topaz WRB weatherproof box sold individually or in a case?
Pack size is 100. That's a case quantity, which suits a service van stock order or a tract job where you're setting a box at every exterior fixture location rather than buying one for a single repair.
