B-LINE B279SQSS4 – Frequently Asked Questions

1) Is the B279SQSS4 post base stainless or plain steel?
Both, in a sense: the base is steel with a type 304 stainless steel finish. Type 304 is the common austenitic stainless used for damp and washdown interiors and general outdoor exposure, which is why this version gets specified over plain electro-galvanized fittings on exterior rooftop or coastal-adjacent strut runs.
2) Does the B-Line B279SQSS4 base come with anchors or bolts?
No. The square post base is sold as the fitting only, model B279SQSS4. Concrete anchors, the hardware that fastens the strut post to the plate, and the strut channel itself are all ordered separately. On a 304 stainless assembly, buyers typically match the fasteners in stainless as well to avoid mixing metals at the anchor point.
3) Is the post base centered or offset on the plate?
Centered. The B279SQSS4 puts the strut post in the middle of the 6 by 6 inch plate, so anchor points sit symmetrically around the post. If your layout needs the post pushed to one edge, against a curb or a wall, a centered base is the wrong choice and you want an offset or edge-style post base instead.
4) What is the B-Line B279SQSS4 square post base used for?
It is a centered square post base for Eaton B-Line strut. The post attaches at the center of the plate, and the plate anchors down to a floor, slab, or other flat surface, so a vertical strut post can be stood up and fastened at its foot. The plate is 6 by 6 inches with a 1.62 inch height.
5) How much footprint do I need to lay out for a B-Line B279SQSS4 base plate?
Allow a 6 inch by 6 inch square footprint. Overall height of the fitting is 1.62 inches, so it adds that much to the finished elevation of anything mounted on the post above it. Weight is 3.14 lb per piece, which matters if you are carrying a pallet of them to a roof.
6) What part number do I give my distributor for the B-Line stainless square post base?
Order Eaton B-Line model B279SQSS4. The SS4 suffix identifies the type 304 stainless version of the B279 square post base, as opposed to the plain or coated steel variants in the same family.
7) Does the B-Line B279SQSS4 carry a UL listing or other certification?
No certification applies to this fitting. It is a mechanical strut support component rather than an electrically rated device, so it is specified on the strut system's structural requirements, not on a listing mark.
