B-Line B110HDG Eaton series strut fittings and accessories, 3.5" Height, 3.5" Length, 1.62" Width, .70lbs, Steel, Offset size 3-1/2 in, Three hole z-support, Thickness 1/4 in, Hot-dipped galvanized

It is an offset Z-shaped steel bracket with three bolt holes, used to step strut or supported runs away from a wall, ceiling, or beam face. The B110HDG gives a 3-1/2 inch offset, so conduit, pipe, or channel lands that far off the mounting surface instead of tight against it. Two of the holes bolt to the structure or strut, the third picks up the offset leg.

3-1/2 inches. That is the stated offset size, and the fitting measures 3.5 inches in height and 3.5 inches in length with a 1.62 inch width, so it sets the supported run about three and a half inches clear of the mounting face. If you need a different standoff you want a different offset size in the same Z-support family, not a modification to this one.

The B110HDG is steel with a hot-dipped galvanized finish, which is the finish specified for exterior, damp, and corrosive-duty work such as rooftops, parking structures, tunnels, and wash-down areas. If the run is indoor dry and painted or plain finishes are acceptable on your job, an electro-galvanized version of the same fitting is the usual choice.

No. It is supplied as the bracket only, so plan on hardware to suit both ends of the connection: channel nuts and bolts where it lands on strut, and anchors or through-bolts where it lands on concrete, block, or steel. For exterior work match the fastener finish to the bracket's hot-dipped galvanizing so you are not pairing plated bolts with a galvanized fitting.

B110HDG, from Eaton's B-Line strut fittings and accessories line. The HDG suffix is the hot-dipped galvanized finish; the 3-1/2 inch offset three hole Z-support is a single configuration, so there are no size or finish choices to specify beyond that number.
