B-LINE 4D21-120PLN – Frequently Asked Questions
1) Is the B-Line 4D21-120PLN galvanized or bare steel?
It is steel with a plain finish, meaning no coating. Plain channel is for dry interior work. For exposed exterior runs, wet areas, or a parking structure, specify a galvanized or pre-galvanized version of the channel instead, because bare steel will rust.
2) Will standard 1-5/8 inch strut fittings fit the B-Line 4D21 channel?
Treat them as different systems. The 4D21 is 2.12 in wide by 1.06 in deep, so it does not match the 1-5/8 in square profile that generic strut fittings are cut for. Stay within the 4Dimension line for nuts and fittings, and if your existing building standard is 1-5/8 in strut, order that profile instead so your stock of nuts and brackets still works.
3) How heavy a gauge is the 4D21 strut channel?
18 gauge steel. That is a light-duty channel, suited to running small conduit, low-voltage cable, signage, or trapeze work with modest loads. For heavy pipe racks or seismic bracing, contractors normally go to a 12 gauge 1-5/8 in strut rather than an 18 gauge shallow channel.
4) What part number do I order for the plain 10 ft 4Dimension channel?
Order manufacturer part number 4D21-120PLN from Eaton B-Line. The number reads out as channel type 4D21, 120 in length, PLN for plain finish. That single part number covers the whole stick; nuts, spring nuts, and fittings are separate line items.
