B-LINE B478HZN – Frequently Asked Questions
1) What is the B-Line B478HZN trolley used for?
The B478HZN is a four bearing light duty trolley assembly with an eye hook, built for running light loads along strut channel. The eye hook is the pick point, so you hang from it directly with a hook, chain, or a threaded rod fitting that will pass through the eye. It rides on four bearings, so it rolls rather than slides.
2) How much clearance do I need for the B478HZN trolley in the channel?
The B478HZN measures 3.93 in height, 3 in length/depth, and 1.625 in width. The 1.625 in width is what sits in the channel opening, and you need to allow for the 3.93 in height so the eye hook and body clear anything mounted below the strut run.
3) Is the B478HZN rated for heavy loads or motor hoists?
No. It is specified as a light duty trolley assembly, so it is not the part for hoisting or heavy rolling loads. Use it for light suspended items that need to move along a channel run. Anything approaching a hoist or a heavy mechanical load calls for a heavy duty trolley.
4) What is the B-Line B478HZN made of and is the finish suitable for a damp area?
Steel, 12 gauge, with an electro-plated finish. Electro-plating is a thin protective coat suited to dry indoor service such as inside a building, plant floor, or mechanical room. For wet, washdown, or outdoor exposure you want a hot dip galvanized or stainless trolley instead.
5) Does the B-Line B478HZN come with the strut channel or mounting hardware?
The B478HZN is the trolley assembly with eye hook only. The channel it runs in, the channel supports, and any chain, hook, or rod you hang off the eye are all separate items you order alongside it.
