B-LINE 4D21-120SS4 – Frequently Asked Questions
1) Is this strut channel stainless or plain painted steel? Can I use it outdoors or in a washdown area?
It is steel in a Type 304 stainless finish. That is the grade normally specified for outdoor, damp, and food or pharma washdown environments where plain painted or pre-galvanized strut would rust at the cut ends. For heavy chloride exposure, such as coastal or pool chemical rooms, Type 316 is the usual step up.
2) What gauge is the Eaton B-Line 4D21 channel?
18 gauge. That is a light-duty strut thickness, suited to smaller conduit runs, instrument racks, sensor and device mounting, and short support spans rather than heavy pipe or large cable tray loads. If you are hanging heavy trapeze runs, step up to a heavier gauge channel.
3) How heavy is a 12 inch piece of this stainless strut?
10.32 lb for the 12 inch piece. Worth knowing if you are ordering by the box for an overhead install or figuring hanger loads on a threaded rod drop.
