B-Line B281ASQSS6 Eaton series strut fittings and accessories, 1.62" Height, 6" Length, 6" Width, 3.30lbs, Steel, Square post base, centered, Fits channel type B22A, B, C, Stainless steel type 316

The B281ASQSS6 is type 316 stainless steel, which is the marine grade with molybdenum added. It holds up in coastal salt air, wash-down areas, water treatment plants and chemical exposure far better than electro-galvanized or hot-dip strut fittings. If your run is indoors and dry, a plain plated version of the same base is the cheaper choice.

It is a 6 inch square plate, 6 by 6 inches, standing 1.62 inches high with the channel already accounted for in that height. Plan for a clear 6 inch square bearing area under each post. The unit weighs 3.3 lb.

Yes. On the B281ASQSS6 the channel socket is centered on the 6 inch square plate, so the post load lands in the middle of the anchor pattern rather than off to one edge. Use the centered version when the upright needs to be plumb over the center of the footing; an offset base is the one to use when the post has to sit tight against a wall or curb.

No anchors or fasteners are included. The B281ASQSS6 is the base fitting only, so you supply the concrete anchors or through bolts for the slab plus whatever hardware attaches the strut into the base. For a 316 stainless base, match the anchors in 316 as well, otherwise you set up galvanic corrosion at the one spot you were trying to protect.

Order Eaton B-Line part B281ASQSS6. The SS6 suffix is what identifies the type 316 stainless version, so dropping it gets you a different finish on the same base geometry.
