B-LINE 4D21SH-120SS6 – Frequently Asked Questions
1) Is the 4D21SH-120SS6 strut channel suitable for outdoor, coastal or wash-down areas?
Yes. It is Type 316 stainless steel, the grade specified for marine, coastal and chemical wash-down environments where plain galvanized or even Type 304 strut corrodes. Water treatment plants, food processing rooms, rooftop and pier-side racking are the usual homes for 316 strut.
2) What does the SH in B-Line 4D21SH mean, and is the channel slotted or solid?
SH is the short-slot hole pattern, so the channel back is punched along its length rather than left solid. That lets you bolt through the back into structure or join runs without field drilling, which is the reason most electrical contractors buy the slotted version for conduit and cable tray support.
3) Is 18 gauge strut channel heavy enough, or do I need a thicker section?
The 4D21SH is rolled from 18 gauge steel, which is a light-duty section next to the 12 and 14 gauge strut used for heavy trapeze and pipe racks. It suits conduit runs, small cable tray, equipment mounting and framing where the loads are modest. For heavy mechanical piping or long unsupported spans, step up to a heavier gauge channel.
4) Do I need stainless hardware with the 316 stainless strut channel?
Yes, match it. Pairing Type 316 stainless channel with plated or zinc hardware puts dissimilar metals together in exactly the wet environment you bought stainless for, and the fasteners fail first. Order stainless strut nuts, bolts and fittings to suit the 1-5/8 inch channel opening.
5) What is the exact part number to order for the 10 foot 316 stainless B-Line strut?
Order Eaton B-Line part number 4D21SH-120SS6. That breaks down as the 4D21 channel profile, SH slotted hole pattern, 120 inch length and SS6 for Type 316 stainless. Distributors cross-referencing should note the 4D21 designation is the 4Dimension series profile.
6) How heavy is a 10 foot stick of 4D21SH-120SS6 strut?
About 10.32 lb per 120 inch length. That is light enough for one person to carry and set overhead, and it matters when you are calculating hanger loads on a long trapeze run or figuring bundle weight for a lift.
