B-LINE 4D21-240SS6 – Frequently Asked Questions
1) Is the 4D21-240SS6 strut channel stainless, and which grade?
It is type 316 stainless steel. Type 316 is the grade specified where chlorides are present, so it is the one to use for coastal installs, wastewater plants, pool rooms, food processing and chemical areas. If the run is indoors and dry, a plain or plated carbon steel channel is the cheaper call and 316 is more corrosion protection than the job needs.
2) What gauge is the B-Line 4D21 channel, and is it a heavy duty strut?
The 4D21 is rolled from 18 gauge steel, which is a lighter gauge strut. It suits smaller conduit runs, single pipe supports and light equipment hangers rather than heavy trapeze racks. For heavy multi-conduit trapezes or large pipe, step up to a 12 gauge channel in the same profile family.
3) Will standard strut nuts and fittings fit the 4D21 channel?
The channel is the 4D21 profile at 2.12 inches across the face, which is the common 1-5/8 inch nominal strut face width, so hardware built for that face width is the range to look in. Match fittings by the 4D21 channel type designation rather than by eye, since the shallow 1.06 inch depth changes what will seat inside the section.
4) Should I use 316 stainless strut or galvanized in a coastal or wash-down building?
Salt air, wash-down chemicals and chloride exposure are exactly where galvanized strut fails first at the cut ends and fastener holes. The 4D21-240SS6 is type 316 stainless right through the section, so a field cut does not open up a corrosion path the way a cut galvanized stick does. Pair it with stainless nuts and bolts, because mixing plated hardware onto stainless channel puts the corrosion back in at the connection.
5) What exact part number do I order for the 20 foot stainless 4D21 strut?
Order Eaton B-Line part number 4D21-240SS6. The suffix reads out as the 4D21 channel profile, 240 inches long, in SS6 type 316 stainless.
