B-Line Eaton series strut fittings and accessories, 1.62" Height, 6" Length, 6" Width, 3.14lbs, Steel, Square post base, centered, Hot-dipped galvaniz

It's a centered square post base for Eaton B-Line strut. The post mounts at the center of a 6 x 6 inch steel plate, so the strut column lands dead center on the anchor pattern rather than offset to one edge. Typical use is standing a strut post up off a floor, roof curb, or concrete pad to carry conduit racks, equipment supports, or rooftop pipe supports.

Footprint is 6 inches by 6 inches, with an overall height of 1.62 inches, and it weighs 3.14 lb. Those numbers matter when you're laying out anchors: you need a clear 6 inch square of flat bearing surface, and the 1.62 inch height is what the strut post sits up off the deck once the base is set.

No. The part you receive is the galvanized steel base itself. Concrete anchors, deck fasteners, and the hardware that ties the strut post into the base are separate items you spec to your substrate and load.

On a centered base like the B279SQHDG, the strut column rises from the middle of the 6 inch square plate, so load is balanced over the anchor pattern and you get equal edge distance on all four sides. Offset and edge bases put the post toward one side, which you use when the column has to sit tight to a wall, curb, or slab edge and you can't get anchors behind it. If you have open flat deck, centered is the one that gives the best anchor geometry.

Order by manufacturer part number B279SQHDG. The HDG suffix is the hot-dipped galvanized finish, so if a drawing calls for HDG strut fittings throughout, this is the matching base. It ships as a single fitting, not a carton set.

It's a mechanical support fitting, not a rated electrical device, and no certification applies to it. It's the steel base that carries a strut post; any listing requirement on your job applies to the conduit, fittings, and enclosures it supports, not to the base plate.

Yes, hot-dipped galvanized is the standard outdoor finish across the Eaton B-Line strut line, so this base coats out the same as HDG channel, clamps, and braces on the same run. Mixing an HDG base under plain or pre-galvanized strut is what causes early rust at the joint, so keep the whole assembly in one finish family.
