B-LINE 4D21-240SS4 – Frequently Asked Questions
1) What are the cross-section dimensions of the B-Line 4D21 strut channel?
The 4D21 profile measures 2.12 inches wide by 1.06 inches high, which is the standard 1-5/8 by 1-1/16 inch shallow strut section. That matters for fittings and strut nuts: hardware sized for a 1-5/8 inch wide channel seats in this profile, and the 1-1/16 inch depth is the half-height section rather than the deeper 1-5/8 by 1-5/8 channel.
2) Is this strut channel stainless steel or just painted steel?
Steel, finished as stainless type 304. That is the grade specified for damp, washdown, coastal, and food-service environments where pre-galvanized or painted strut would corrode. If you are running in a dry indoor ceiling, a plain galvanized channel of the same 4D21 profile does the same structural job.
3) Do the strut nuts, fittings, and clamps come with this channel?
No. This is the bare 240 inch channel only. You order the spring nuts, channel nuts, post bases, angle fittings, beam clamps, and conduit straps separately, and in a corrosive or washdown area you want those in stainless as well so you are not pairing a type 304 channel with plated hardware that rusts first.
4) How much does a 20 foot stick of 4D21-240SS4 weigh for handling and hanger sizing?
20.64 lb for the full 240 inch stick, roughly 1 lb per foot. Light enough for a one-man carry, and worth adding into your dead load when you size the rod and anchor for a trapeze or ceiling hanger.
5) What is the exact part number to order this stainless 4Dimension strut?
Order Eaton B-Line part number 4D21-240SS4. The number reads out as the channel profile (4D21), the length in inches (240), and the material (SS4 for type 304 stainless). Useful when a distributor or submittal package needs the manufacturer designation rather than a description.
