B-LINE 4D21S-120PLN – Frequently Asked Questions
1) Is the 4D21S strut channel slotted or solid back?
It is a slotted channel. The S in 4D21S is the hole pattern designation, so the back of the channel carries the slot pattern rather than being solid. That lets you bolt through the back into structure or joint two pieces without drilling on site.
2) What finish is the B-Line 4Dimension 4D21S channel, and can I use it outdoors?
Plain finish steel, meaning bare uncoated mill steel with no galvanizing or paint. Keep it to dry interior work. For exterior, wet, or corrosive locations you want a pre-galvanized or hot dip galvanized version of the same 4D21 profile instead, or the channel will start rusting.
3) Will standard strut nuts and fittings fit the B-Line 4D21 channel?
The 4D21 is a 2.12 inch wide profile, which is wider than the common 1-5/8 inch strut face. Fittings, spring nuts and clamps sized for 1-5/8 inch channel are not the right hardware for it. Order nuts and fittings called out for the 4Dimension 4D21 channel so the nut seats correctly in the lips.
4) What is the exact part number to reorder this Eaton B-Line strut so it matches what is already installed?
Order Eaton B-Line 4Dimension series 4D21S-120PLN. Broken down: 4D21 profile, S slotted back, 120 inch length, PLN for plain finish. If the existing run is galvanized rather than bare steel the finish suffix will differ, so check an installed stick before matching.
5) Can one person carry and hang a 10 foot stick of this strut?
At 10.32 lb per 120 inch stick, it is a one man carry, though the length makes two hands and a ladder partner sensible overhead. The light 18 gauge, 1.06 inch deep section is why it is that manageable compared with a full depth heavy gauge channel.
