B-LINE 4D21-240PLN – Frequently Asked Questions
1) Is the 4D21-240PLN strut channel galvanized or bare steel?
Bare. The 4D21-240PLN is steel with a Plain finish, meaning no zinc or paint coating from the factory. Plain strut is intended for dry interior runs or for jobs where the channel gets painted after install. For damp, exterior, or corrosive locations you want a pre-galvanized or hot-dip galvanized channel instead.
2) Does the 4D21 strut channel come with nuts, bolts, or mounting hardware?
No. The 4D21-240PLN is the bare channel stick only. Channel nuts, spring nuts, threaded rod, end caps, post bases, and any braces or fittings are ordered separately, so build those into your takeoff before the job goes out.
3) Is the 4Dimension 4D21 strut channel UL listed or certified to a specific standard?
The 4D21 channel is supplied as a general-purpose steel support channel with no certification called out on the product record. Where a job requires listed support hardware, confirm the requirement against the approved submittal for that installation before you commit the material.
4) Can I cut the 20 foot strut channel down on site?
Yes, 18 gauge steel channel cuts readily with a bandsaw, chop saw with a metal blade, or portable band saw. Because the 4D21-240PLN carries a Plain finish with no protective coating, deburr and prime or paint the cut ends if the run is anywhere that will see moisture.
