B-LINE 18186 SCG – Frequently Asked Questions

1) Can the B-Line 18186 SCG junction box be used outdoors?
Yes. The 18186 SCG is a Type 3/3R enclosure, which is the rating for outdoor use against rain, sleet, windblown dust and external ice formation. It is also suitable for Type 12 indoor dust and dripping-liquid service. The galvanized steel body carries an oil-resistant gasket and gasketed screws to hold that seal. It is UL 50 listed.
2) What are the box dimensions on the 18186 SCG, and will it take a 6 inch deep gutter run?
It measures 18 inches high by 18 inches wide with a 6 inch depth, so you have 6 inches of interior clearance behind the cover for conductors, terminal blocks or a small DIN rail. The square 18 x 18 face makes it a common pull and splice box where two conduit runs change direction.
3) Does this B-Line enclosure come with mounting feet or brackets?
No. The 18186 SCG ships with no mounting provisions, so there are no factory mounting holes, feet or panel brackets on it. It is a surface mount enclosure, which means you supply the wall brackets or external mounting feet, and you drill nothing through the back wall if you want to keep the Type 3R seal intact. Budget the mounting kit as a separate line on the order.
4) Is the cover hinged or does it screw on?
Screw cover. The 18186 SCG uses a removable screw-on cover with gasketed screws rather than a hinged door, so you need clearance in front of the box to lift the cover off and a screwdriver every time you open it. For enclosures you expect to open frequently, a hinged or clamped-cover version is the easier choice.
5) How heavy is the 18186 SCG, and how thick is the steel?
30 pounds, built from 14 gauge galvanized steel. That weight matters for mounting: on stud wall or block you want anchors rated well past 30 pounds plus whatever conduit and conductors load the box. The 14 gauge wall is heavier than the 16 gauge typical of light-duty boxes, which is why it holds a gasket seal without oil-canning.
6) Does the 18186 SCG come with conduit knockouts?
No knockouts are provided. The enclosure has no mounting provisions and the screw cover design leaves the walls blank, so you field-punch the conduit entries where your runs land. Use a hole punch sized to your fittings and seal each entry with a Type 3R rated hub or sealing locknut, otherwise the gasketed cover is doing you no good.
7) What is the exact part number to order this Eaton B-Line box, and where is it made?
Order it as B-Line 18186 SCG, the medium single door SCG screw cover enclosure. It is made in the US.
