B-LINE B478PZN – Frequently Asked Questions
1) What is the B-Line B478PZN trolley used for?
The B478PZN is a four bearing light duty trolley assembly that rides inside strut channel, giving you a rolling attachment point for light loads, hangers, or movable supports along a run of channel. The bearings are plastic, which is why it is rated as light duty rather than a heavy rolling load.
2) Is the B478PZN trolley steel, and how is it finished for corrosion?
The body is 12 gauge steel with an electro-plated finish. That plating suits dry indoor and protected interior runs; for washdown, exterior, or corrosive areas you want a hot dip galvanized or stainless trolley instead.
3) Why plastic bearings instead of steel rollers on a strut trolley?
Plastic bearings on the B478PZN roll quieter and will not gall against the plated channel lips, which is why it is classed light duty. If you are moving a heavy fixture or a frequent-cycle load, step up to a steel roller trolley rather than this one.
4) What is the exact part number to order this B-Line trolley under?
Order it as B-Line B478PZN. That is the manufacturer part number, and the assembly ships as a single model with no finish or size options to specify.
5) Does the B-Line B478PZN carry any listing or certification for spec work?
No certification is carried on the B478PZN trolley assembly, so if your drawing calls for a listed or labeled component on that support, this part will not satisfy that line item.
