B-LINE B281ASQZN – Frequently Asked Questions
1) Will a B-Line B281ASQZN post base fit 1-5/8 inch strut channel?
Yes. The B281ASQZN square post base is built for B-Line channel types B22A, B and C, which are the 1-5/8 inch wide strut profiles. It seats the end of the strut post and bolts through to the floor or slab below.
2) Do anchors or bolts come with the B281ASQZN strut post base?
No. The B281ASQZN ships as the steel base plate alone at 3.3 lb. You supply the floor anchors sized to your substrate (wedge anchors or drop-in anchors for concrete, through bolts for steel deck) and the hardware that fastens the strut into the base.
3) How much floor space does the B281ASQZN base plate take up?
The plate is 6 inches by 6 inches square and stands 1.62 inches tall. Allow a full 6 inch square footprint plus clearance for your anchors when laying out post locations near walls or curbs.
4) What is the difference between a centered post base and an offset one?
Centered means the strut socket sits in the middle of the 6 x 6 inch plate, so the anchor holes surround the post evenly and load is shared in all directions. That is what you want for a freestanding post in open floor, such as a rooftop pipe stand or an equipment frame leg. If the post has to sit tight against a wall or curb face, an offset or edge base is the better choice because it moves the anchors to one side of the strut.
5) Is the B-Line B281ASQZN post base suitable for outdoor or wet locations?
It is steel with an electro-plated finish. Electro-plated zinc is a thin coating suited to dry indoor and protected locations. For rooftops, exterior pads, parking structures or washdown areas, specify a hot-dip galvanized or stainless post base instead.
