B-LINE B173ZN – Frequently Asked Questions

1) What is the B-Line B173ZN four hole clevis used for in a strut system?
The B173ZN is a four hole clevis fitting from the Eaton B-Line strut fittings and accessories line. It bolts into strut channel to form a pivoting or hinged connection point in a support assembly, with four bolt holes on 1-21/32 inch center spacing and a channel depth of 3-5/16 inches. It is 1/4 inch thick steel with an electro-plated finish, so it is intended for indoor, dry support work rather than exterior or corrosive locations.
2) Will the B173ZN clevis bolt into standard 1-5/8 inch strut channel?
The hole pattern is on 1-21/32 inch centers, which is the spacing used across 1-5/8 inch B-Line strut channel, and the fitting is dimensioned for a 3-5/16 inch channel depth. If your run is 1-5/8 inch wide channel of that deeper profile, the bolt pattern lines up. On a shallower 1-5/8 by 1-5/8 channel the hole spacing still matches, but check the seating depth before you commit the run.
3) Is the electro-plated finish on this B-Line clevis suitable for outdoor or wet locations?
No. Electro-plated zinc is a thin sacrificial coating meant for dry interior service. For rooftop, exterior, wash-down, or coastal work you want a hot-dip galvanized or stainless fitting instead. Specifying the electro-plated part outdoors is a common way to get rust bleed within a season.
4) How thick is the steel on the B-Line B173ZN, and is it heavy enough for structural pipe support?
It is 1/4 inch thick steel, which is the heavy end of the strut fitting range compared with the 3/16 and lighter formed brackets. That thickness is what lets a clevis carry a pivoting or suspended load rather than just brace a run. The piece weighs .71 lb.
5) What are the overall dimensions of the B173ZN clevis for layout planning?
3.31 inches height, 3.31 inches length, and 1.87 inches width. When you are laying out a ceiling grid or a congested rack, that 1.87 inch width is the number that matters for clearance between parallel runs, and the 3.31 inch dimensions set how far the fitting projects off the channel face.
6) What do I need to order with the B173ZN clevis to complete the connection?
The clevis itself is the bracket only. You will need channel nuts and bolts sized to the strut for the four mounting holes, plus the clevis pin or bolt and nut for the pivoting end, and whatever rod or hanger the clevis is picking up. None of that hardware is part of the B173ZN.
7) What is the exact part number for the B-Line four hole clevis so I can match it on a submittal?
Order it as Eaton B-Line B173ZN. The ZN suffix denotes the electro-plated zinc finish, so if a drawing calls for a different coating on the same body you are looking at a different suffix, not this part.
