B-LINE B279FLSS4 – Frequently Asked Questions
1) What is the Eaton B-Line B279FLSS4 post base used for?
It's a rectangular post base that mounts a strut post to a flat surface such as a concrete pad, deck, or steel plate. The "flush to side" style means the base plate sits flush against the side face of the strut rather than centering it, so the post can be set tight to the edge of a curb or wall. Footprint is 8 by 3 inches with a 1.62 inch height, and it weighs 2.3 lb.
2) Is the B279FLSS4 stainless steel or just plated steel?
Type 304 stainless steel. The material is listed as steel with a type 304 stainless finish, which is what you want for outdoor rooftop supports, washdown areas, coastal exposure, and wastewater plants where an electro-galvanized or pre-galvanized base would rust out at the concrete line.
3) Can I use this post base where the strut has to sit right at the edge of a curb?
Yes, that's exactly what the flush-to-side design is for. The plate extends to one side of the post rather than surrounding it, so the strut face can sit flush at an edge or against an adjacent wall while the 8 inch long plate picks up anchor points away from the edge.
4) Does the B279FLSS4 post base come with anchors or bolts?
No. The base is supplied as the fitting only. You supply the concrete anchors or through-bolts for the floor side and the channel nuts and bolts for the strut side. On stainless installations, match the fasteners to the 304 stainless base so you don't set up galvanic corrosion at the joint.
5) What part number do I order for a flush-to-side stainless strut post base?
Order Eaton B-Line model B279FLSS4. That single catalog number covers the rectangular flush-to-side post base in type 304 stainless.
