B-LINE 4D21S-120GLV – Frequently Asked Questions
1) Can I use pre-galvanized strut channel outdoors or in a wet area?
Pre-galvanized steel is a mill-applied zinc coating and it is intended for indoor and protected dry locations, mechanical rooms, ceiling spaces, electrical rooms. For exterior runs, parking structures, wash-down areas or anywhere with regular moisture, specify hot dip galvanized after fabrication or stainless instead. The 4D21S-120GLV is the pre-galvanized version.
2) Will standard 1-5/8 inch strut nuts and fittings fit the 4D21 channel?
No. The 4Dimension 4D21 section is 2.12 inches wide with a 1.06 inch depth, which is not the conventional 1-5/8 inch strut profile, so channel nuts and clamps made for 1-5/8 inch strut are not a match. Order 4Dimension series fittings sized to the 4D21 channel.
3) How do I order the Eaton B-Line 4Dimension channel and what is the part number?
Order by manufacturer part number 4D21S-120GLV from Eaton's B-Line series. The code reads out as 4D21 channel type, S slotted hole pattern, 120 inch length, GLV pre-galvanized finish. Brackets, channel nuts, hardware and end caps are separate line items and are not supplied with the channel.
4) Can strut channel be cut to length on site?
Yes, the 4D21S ships as a 120 inch stick of 18 gauge steel and is routinely cut down with a bandsaw or chop saw. Once you cut it the exposed steel edge has no zinc on it, so on pre-galvanized material touch the cut end with a cold galvanizing compound if the run is anywhere humidity will find it.
