B-LINE N525ZN – Frequently Asked Questions
1) What thread size is the B-Line N525ZN spring nut, and will it take 5/8 inch all-thread rod?
The B-Line N525ZN channel nut is tapped 5/8"-11, so it takes 5/8 inch coarse-thread all-thread rod or a 5/8"-11 bolt. It will not accept 1/2"-13 or 3/8"-16 rod, which are the other common trapeze hanger sizes, so match the rod before you order.
2) Does a spring nut need to be installed before the strut is up, like a plain channel nut?
No. The N525ZN is a spring nut, which means it carries a spring on the back that holds the nut in position in the channel while you set your rod or bolt. You drop it into the strut anywhere along the run, quarter-turn it so the grooved ends bite the channel lips, and it stays put hands-free. A plain (no-spring) channel nut has to be held or slid in from the end. That is the practical reason to spec the spring version on overhead trapeze work.
3) Is the B-Line N525ZN channel nut rated for outdoor or wet locations?
It is a steel nut with an electro-plated zinc finish, which is a general indoor and dry-location finish. For exterior, damp, or corrosive runs, look at a hot dip galvanized or stainless channel nut in the same 5/8"-11 thread instead.
4) Can I use the B-Line N525ZN in another manufacturer's strut channel?
It is built for Eaton B-Line series strut channel. Standard 1-5/8 inch channel from other makers shares the same lip profile, so a 5/8"-11 spring nut of this size generally seats the same way, but if your existing run is a shallow or non-standard profile, confirm the channel type first.
5) What else do I need to hang threaded rod off strut with this nut?
The N525ZN is the nut only. You supply the 5/8"-11 all-thread rod, the strut channel itself, and any washers or hex nuts you want at the rod end. Nothing is bundled with it.
6) What are the dimensions of the B-Line N525ZN spring nut?
It measures 1.375 in by .85 in by .825 in and weighs .088 lb each. The .85 in dimension is what matters for the channel: it drops into standard 1-5/8 inch strut opening and turns to lock. Use the .088 lb figure when you are totalling hanger weight on a long run.
7) What is the B-Line part number for the 5/8"-11 zinc spring channel nut?
Order as B-Line N525ZN. The ZN suffix is the electro-plated zinc finish; the 525 is the 5/8"-11 thread.
