B-Line Eaton series strut fittings and accessories, 1.62" Height, 3.25" Length, 1.62" Width, .34lbs, Steel, Two hole splice plate, Hot-dipped galvaniz

The finish is hot-dipped galvanized, which is the coating specified for exterior, damp, and corrosive locations such as rooftops, parking structures, wash-down areas, and unconditioned mechanical spaces. For dry indoor strut runs an electro-galvanized or painted plate is the usual choice, but hot-dip is the one to order when the run sees weather.

It measures 3.25 in in length, 1.62 in in height, and 1.62 in in width. The 1.62 in dimension matches the face width of standard 1-5/8 in strut channel, so the plate sits flush on the channel face without overhanging the edges.

A two hole plate like the B340HDG takes one bolt into each length of channel, which is enough for a straight splice on a light to moderate support run. Where the joint sits in the middle of a span or carries more load, a longer four hole plate spreads the connection over two bolts per side and stiffens the splice. The B340HDG is the compact option at 3.25 in long, so it also suits tight spots where a longer plate will not land.

Order Eaton B-Line part number B340HDG. The HDG suffix is the hot-dipped galvanized finish; the same plate pattern is offered in other B-Line finishes under different suffixes, so quote the full B340HDG designation if you need the galvanized version.

Yes, it bolts to any standard 1-5/8 in strut channel regardless of that channel's finish, since the 1.62 in plate width matches the channel face. Mixing finishes is a corrosion question, not a fit one: in an exterior or damp run, pairing a hot-dip plate with plain steel channel means the channel rusts first, so match finishes where the run is exposed.
