B-LINE 4D21-240GRN – Frequently Asked Questions
1) Is the 4D21 half-height channel or full 1-5/8 inch deep strut?
Half height. At 1.06 in tall it is the shallow profile, which is what you want where ceiling or wall clearance is tight, for conduit racks and light equipment supports. Where the spec calls for a full depth 1-5/8 in channel for span or load, order the deeper 4Dimension profile instead of this one.
2) What gauge steel is the 4D21-240GRN strut channel?
It is 18 gauge steel. That is the lighter end of the strut range, suited to light duty pipe and conduit runs, small trapeze supports and equipment mounting rather than heavy mechanical loads. Contractors carrying heavy pipe on long spans normally step up to 12 gauge channel.
3) What does the GRN in 4D21-240GRN mean, and is that finish suitable for outdoor use?
GRN is the Dura Green finish, a coated finish on the steel channel rather than bare or plain steel. It gives a painted barrier against handling and general shop conditions. For aggressive wet or corrosive environments, buyers typically specify hot dip galvanized or stainless channel instead.
4) Does the B-Line 4D21 strut channel come with fittings, nuts or hardware?
No. The 4D21-240GRN is the bare channel stick only. Strut nuts, clamps, brackets, post bases and threaded rod are ordered separately, sized to the 1-5/8 in nominal strut opening.
