B-LINE B379ZN – Frequently Asked Questions

1) What are the dimensions of the B-Line B379ZN trolley assembly?
It measures 3.37 in height, 3.31 in length/depth and 1.62 in width. The 1.62 in width is the figure to check first, since that is what has to pass into the channel opening of the strut you plan to run it in.
2) What is the Eaton B-Line B379ZN used for?
The B379ZN is a four bearing trolley assembly from the Eaton B-Line strut fittings and accessories line. It rides inside strut channel on four bearings so a load can be moved along the run rather than fixed at one point. It is a steel assembly weighing 8.89 lb.
3) Is the B379ZN trolley finished for use in damp or outdoor locations?
The finish is electro-plated zinc over steel. That is a general indoor, dry-location plating. For wet, corrosive or exterior runs, specify a hot-dip galvanized or stainless trolley instead.
4) What should I order with a B379ZN trolley to complete the run?
The B379ZN is the trolley only. You still need the strut channel it rides in, the channel supports or hangers to carry that run, and whatever rod, clevis or attachment hardware connects the load to the trolley. Nothing beyond the four bearing trolley assembly itself is included.
5) Is a trolley the right choice, or should I use a fixed strut nut?
Use the B379ZN four bearing trolley where the supported item has to travel along the channel, a moving pipe support, a sliding equipment mount, a light material handling run. If the load simply hangs in one spot, a channel nut or strut clamp is the cheaper and stiffer way to do it. A trolley adds rolling hardware you do not need on a static hanger.
6) Does the Eaton B-Line B379ZN carry a listing or certification?
No certification applies to the B379ZN trolley assembly. If your submittal requires a listed or labeled component for the moving support, this one will not satisfy that line item.
7) How do I confirm I am ordering the right B-Line trolley part number?
Order by manufacturer part number B379ZN from Eaton's B-Line strut fittings and accessories line. The ZN suffix is the electro-plated zinc version.
