B-Line Eaton series strut fittings and accessories, 3.5" Height, 6" Length, 6" Width, 4.00lbs, Steel, Square post base, centered, Post base for B22A,

Centered. The channel socket sits in the middle of the 6 by 6 plate, so the post load lands over the center of the anchor pattern. If your design needs the post set to one edge of the plate, say tight against a wall or curb face, a centered base is the wrong choice and you want an offset post base instead.

It is a 6 inch by 6 inch square plate with a 3.5 inch height, weighing 4 lb. Use the 6 by 6 dimension to lay out your anchor pattern and to confirm you have clearance on a curb or housekeeping pad before you set the post.

No. The post base is the steel plate and socket only, 4 lb as shipped. Concrete anchors, the bolts or nuts that fasten the channel into the base, and any leveling shims are separate line items you need to add to the order. Pick the anchor to suit your slab and the load, not the base.

It is built for that kind of work: steel with the DURA GREEN corrosion-resistant finish, sized for B22A, B and C combination channel, which is what most rooftop and yard-mounted post frames are built from. Confirm the post you are erecting is one of those three channel profiles, because the socket is sized for them and will not accept a different strut section.

DURA GREEN is the B-Line corrosion-resistant coating, and it is what this steel post base ships with. Color match matters on an exposed run, so if the rest of your strut and fittings on the job are plain electrogalvanized or hot-dip, this part will not blend with them visually even though it bolts up the same.

Order B-Line B281SQGRN. The SQ denotes the square centered base and GRN the DURA GREEN finish. There is one configuration, so there is no size, hand or finish to specify beyond that number.
