B-LINE 4D21S-120GRN – Frequently Asked Questions
1) Is the 4D21 strut channel solid or slotted on the back?
Hole pattern S, which is the slotted back. Slots let you run bolts through the channel web into the structure at points you choose rather than being locked to a fixed hole spacing, and they give you some slide adjustment when you are lining up a run of trapeze hangers. If you want an unpierced back for maximum section strength, you want the solid version of the 4D21 instead.
2) What is the green finish on the B-Line 4D21S-120GRN, and where can it be used?
It is Dura Green, Eaton B-Line's green coated steel finish. The coating is a painted/coated carbon steel system, so it suits dry interior work and light protection in covered areas. For exposed exterior runs, wash down rooms or anywhere corrosive, buyers normally step up to hot dip galvanized or stainless channel rather than a coated finish.
3) Does the B-Line strut channel come with nuts, bolts or hanger hardware?
No. The 4D21S-120GRN is the bare 120 inch channel section only. Spring nuts, hex bolts, washers, end caps, closure strips, threaded rod and any fittings or anchors for the job are all ordered separately. Plan the fastener count off your hanger spacing before you place the order so you are not waiting on nuts with the strut already on site.
4) Can I cut the 120 inch strut channel down on site?
Yes, 18 gauge coated steel channel cuts readily with a bandsaw, chop saw with a metal blade or a portable band file. Cut ends lose the Dura Green coating, so hit them with a cold galvanizing or matching touch up paint if the run sits anywhere damp, and file the burr so spring nuts still slide the full length.
