B-Line Eaton series strut electrical accessories, 2.5" height, 5.62" length, 1.62" width, Steel, Includes 1 B718 and 4 B719, Universal junction box, B

The B718-4ZN mounts to B22, B24 and B26 strut channel. If your run is a different B-Line channel profile, this kit is not the one to order.

One B718 junction box plus four B719 pieces ship together under the B718-4ZN part number, so you get the box and its four mating components in a single order rather than sourcing them separately.

Yes, the B718-4ZN carries a UL Listed marking, which is what most AHJs look for on a junction box in a commercial or institutional install.

2.5 in height, 5.62 in length/depth and 1.62 in width. Weight is 2.8 lb, which matters if you are hanging several off a single trapeze run and totalling the load.

Steel body with an electro-plated zinc finish. That finish suits dry interior work, mechanical rooms and conditioned spaces. For wet, exterior or washdown areas, specify a hot-dip galvanized or stainless strut accessory instead.

A strut-mounted box like the B718 attaches directly to the channel you already have overhead, so you do not add separate standoffs or a backplate. That is the reason it goes on trapeze and rack runs in mechanical rooms and plant ceilings. Where you are boxing into drywall or a stud bay, a conventional device box is the simpler and cheaper choice, since this is built around B22, B24 and B26 channel.

Each order of the B718-4ZN covers one junction point, since the kit is one B718 box with four B719 pieces. For an MRO or facility standard, count one kit per box location on your B22, B24 or B26 runs and order in that multiple so every opening gets the same assembly.
