B-LINE 12128 SCG – Frequently Asked Questions

1) What are the box dimensions on the B-Line 12128 SCG enclosure?
12 inches high, 12 inches wide and 8 inches deep, which is where the 12128 designation comes from. Plan for 8 inches of clearance off the wall face plus whatever the conduit runs need. It weighs 16.3 lb empty, so a single person can hang it.
2) Does the B-Line 12128 SCG come with mounting feet or brackets?
No. It's ordered with no mounting provisions, so there are no external feet, brackets or mounting ears in the box. It's a surface mount enclosure, so you supply the mounting hardware and anchors. Never drill the back or sides to mount it outdoors, that breaks the Type 3R seal.
3) Is there a back panel included with this Eaton B-Line screw cover enclosure?
The 12128 SCG is supplied as the enclosure body and screw cover only. It is a small single door style box with no inner panel and no mounting provisions, so if you need a subpanel for terminal blocks or devices, order one separately.
4) Does the 12128 SCG junction box come with knockouts?
No knockouts. Screw cover SCG boxes ship blank so the installer locates conduit entries to suit the run. Punch or hole-saw only the surfaces you need and use listed watertight hubs or fittings if you want to hold the Type 3R rating outdoors.
5) What gauge steel is the B-Line 12128 SCG made from, and will it rust outside?
14 gauge galvanized steel. The galvanizing is the corrosion protection, and the box ships unfinished in its natural grey, no paint. For coastal or washdown chemical exposure a stainless or non-metallic Type 4X enclosure is the better call.
6) Screw cover or hinged door junction box, which should I use?
A screw cover box like the 12128 SCG suits a pull or junction point you rarely open, since the whole cover comes off and the gasketed screws must be reset to keep the seal. If a tech opens the box routinely for testing or terminations, a hinged cover enclosure is easier to work in because the cover stays captive.
7) Is the B-Line 12128 SCG made in the USA?
Yes, country of origin is the US, which matters on public and institutional jobs carrying domestic sourcing requirements. Order it by manufacturer part number 12128 SCG.
