B-LINE B557ZN – Frequently Asked Questions

1) What is the Eaton B-Line B557ZN splice plate used for?
The B557ZN is a three hole splice plate for joining strut channel end to end. You bolt it across the joint using channel nuts so two runs of strut carry through as one continuous run. It is a flat steel plate, not an angle or corner fitting, so it splices in a straight line only.
2) Is the B557ZN splice plate suitable for outdoor or wet locations?
It is steel with an electro-plated zinc finish, which is a light indoor-duty coating. For dry interior mechanical rooms, ceilings, and electrical rooms it is fine. For exterior, damp, or corrosive environments, specify a hot-dip galvanized or stainless strut fitting instead.
3) Should I use a three hole splice plate or a four hole plate to join strut?
A three hole plate like the B557ZN gives you three fastening points across the joint and is the common choice for standard splices in light and medium duty runs. Go to a longer four hole or six hole plate when the splice falls in an unsupported span or carries heavier load, since more bolts spread the shear over more of the channel. For corners or right angle transitions you want an angle fitting, not a flat splice plate.
4) What is the manufacturer part number for this Eaton B-Line splice plate?
The part number is B557ZN. The ZN suffix indicates the electro-plated zinc finish; B-Line uses different suffixes for other finishes on the same plate body.
