B-LINE 4D21SH-240GRN – Frequently Asked Questions
1) Is 18 gauge strut strong enough for hanging conduit racks and trapeze supports?
18 gauge is the light-duty end of the strut range. On the 4D21 profile it is intended for branch conduit runs, small pipe, cable tray droppers, and light equipment mounting where spans between supports are short. For heavy trapeze hangers, long unsupported spans, or stacked multi-conduit racks, step up to a 12 gauge full-height 1-5/8 by 1-5/8 channel instead.
2) Is Dura-Green strut channel suitable for damp or corrosive areas, or should I use galvanized?
Dura Green is a painted steel finish, an enamel-type coating over 18 gauge steel. It handles dry interior electrical and mechanical support well and gives you color coding on the job. For wet, exterior, or washdown areas, a hot dip galvanized or stainless strut is the better call, since a painted finish will fail where it gets nicked or stays wet.
3) Can I match B-Line 4D21SH-240GRN to green strut already installed in my building?
The finish is B-Line Dura Green, so it will match other Eaton B-Line Dura Green strut and fittings on existing runs. Green painted strut from another manufacturer may read as a different shade. For a visual match down a corridor, keep to the same 4D21 profile too, since a full-height channel beside a 1.06 inch deep one is obvious once it is up.
