B-LINE B280SS4 – Frequently Asked Questions

1) What strut channel does the B-Line B280SS4 post base fit?
The B280SS4 square post base is made for B22 channel, which is the 1-5/8 inch wide, 3-1/4 inch deep back-to-back strut in the B-Line series. If your run is single-height B22 (1-5/8 x 1-5/8) or a different profile, this base is not the right footing for it.
2) Is the B-Line B280SS4 post base stainless or plain steel?
Type 304 stainless. The material is listed as steel with a stainless steel type 304 finish, which is why it carries the SS4 suffix. That makes it suited to wet, washdown, and exterior work where a plain electrogalvanized base would rust at the anchor holes.
3) What size footprint does the B280SS4 post base need on the slab?
The base plate footprint is 6 by 6 inches, and the fitting stands 3.5 inches tall overall. Lay out your anchors inside that 6 inch square and allow the 3.5 inch height when you figure finished post elevation.
4) What does centered offset mean on a square strut post base?
On the B280SS4, the channel saddle sits offset rather than flush with one edge, so the post lands centered over the 6 by 6 inch plate. That gives you even anchor spacing around the post instead of the lopsided pattern you get from an edge-mount base, which matters when you are anchoring into a slab edge or a curb.
5) Does the B280SS4 post base come with anchors or bolts?
No. The B280SS4 is the base fitting only, at 3.92 lbs. Concrete anchors, the channel nuts and bolts that fasten the B22 strut into the saddle, and any shims are all separate, so add them to the order if you are building the footing from scratch.
6) Can I use the B280SS4 stainless post base with galvanized strut?
Mechanically yes, as long as the channel is B22 profile. Be aware you are mixing metals: pairing a type 304 stainless base with zinc-plated or hot-dip strut and hardware in a wet or coastal location sets up galvanic corrosion at the joint. For outdoor runs, most specs keep the base, channel, and fasteners all stainless.
