B-Line 16164 RTSC NK Eaton series Type 3/3R junction boxes

Yes. The Eaton B-Line 16164 RTSC NK is a Type 3R enclosure, so it is built for outdoor use against falling rain, sleet and snow. It also carries a rain hood over the cover opening to shed water away from the seam. What 3R does not cover is washdown or hose-directed water, so if the location sees pressure spray or heavy dust you want a Type 4 or 12 box instead.

It measures 16 inches high by 16 inches wide with a 4 inch depth, so it is a square pull or junction box with a shallow back box. Plan your conduit entries and gutter bends around that 4 inch interior depth, it is tight for large-radius bends on big feeders.

No. The NK in 16164 RTSC NK means no knockouts, so the box ships blank and you punch your own conduit entries where the run needs them. That is the version you want on a field-routed job; if you would rather have factory openings, order a knockout version instead of this one.

It is built to UL 50, the standard covering enclosures for electrical equipment, and it is a US-made product. That plus the Type 3R rating is normally what an inspector or a submittal reviewer is looking for on an outdoor pull box.

The cover is a flanged screw cover with plated screws, so it lifts straight off once the screws are out rather than swinging on a hinge. At 13 lb total for the enclosure, the cover alone is easy to handle, but plan on a second set of hands or a ledge if you are pulling it off a high mount, since nothing holds it once the last screw is loose.

Surface mount, using embossed thru holes in the back of the box. The embossing keeps the fastener heads off the mounting surface so water does not track into the hole. Fasteners are not part of the enclosure, so pick anchors to suit your substrate and rate them for the 13 lb box plus whatever you are landing inside it.

Body is 16 gauge carbon steel with a painted finish in ANSI 61 grey. Painted steel is fine for normal exterior and damp-location work, which is what the 3R rating covers. In coastal salt air, wastewater rooms or chemical exposure, steel will eventually give up its coating, and a stainless or non-metallic enclosure is the better call there.

ANSI 61 grey is the standard light grey used across most commercial electrical gear, so this box will read the same as typical panelboards, disconnects and other B-Line enclosures already on the wall. Useful if you are standardizing a facility and want added pull boxes to disappear into the existing lineup rather than being repainted.
