B-LINE B281MSQSS4 – Frequently Asked Questions
1) What strut channel does the B-Line B281MSQSS4 post base fit?
The B281MSQSS4 is a square post base made for B22-2PL channel, which is the back-to-back double strut profile. If you are standing up a single-piece channel or a different B-Line profile, this is not the base to order.
2) Is the B281MSQSS4 post base stainless, and will it hold up outdoors?
It is type 304 stainless steel, so it suits exterior and washdown mounting where a plain or electro-galvanized base would rust at the bolt holes. Type 304 is the general-purpose stainless grade; for chloride-heavy coastal or pool environments a 316 base is the usual step up.
3) What footprint do I need to leave for a B281MSQSS4 base plate?
The plate measures 6 inches by 6 inches with an overall height of 3.5 inches. Lay out your anchors inside that 6 inch square, and allow the 3.5 inch rise when you cut post length to a finished height.
4) Does the B281MSQSS4 mount the strut in the middle of the plate or off to one side?
Centered. The channel socket sits in the middle of the 6 by 6 inch plate, so anchor loading is symmetrical about the post. If your layout needs the post tight to an edge or wall, you want an offset base instead.
5) Do anchors come with the B281MSQSS4 post base?
No. The B281MSQSS4 is the base casting only. Concrete anchors or through bolts, plus the hardware fastening the B22-2PL channel into the socket, are bought separately, and in stainless applications buyers usually match them to the 304 base.
6) What part number do I quote for the Eaton B-Line square centered stainless post base?
Order it as B-Line B281MSQSS4. The SS4 suffix is the type 304 stainless version of the square centered post base for B22-2PL channel.
