B-LINE 4D21-120YZN – Frequently Asked Questions
1) What gauge steel is the Eaton B-Line 4D21 channel, and is it heavy enough for pipe hanging?
It's 18 gauge steel. That's a lighter wall than the 12 gauge stock commonly used for structural trapeze runs, so 4D21 suits light-duty work: small conduit runs, low-voltage and data cable support, light equipment mounting and bracketry. For heavy pipe trapezes or long unsupported spans, step up to a 12 gauge deep-section channel.
2) What is the exact part number to order for this Eaton B-Line strut channel?
Order it as Eaton B-Line 4D21-120YZN. The number reads directly: 4D21 is the channel profile, 120 is the 120 inch length, and YZN is the yellow zinc chromate finish. Quoting the full string avoids getting a different length or a different plating on the same profile.
3) Can this strut channel be cut down on site?
Yes. It's 18 gauge plated steel supplied in 120 inch sticks, so it cuts cleanly with a chop saw or band saw for shorter drops and trapeze pieces. Anywhere you cut, the yellow zinc chromate plating is gone at the cut edge, so hit the ends with cold galvanizing or a zinc-rich paint if the location is at all damp.
