B-LINE B281SQHDG – Frequently Asked Questions
1) Can a B-Line B281SQHDG post base be used outdoors or in a wet area?
It's steel with a hot-dipped galvanized finish, which is the finish B-Line uses for exterior and damp locations such as rooftop equipment supports, yard racks and parking structures. Painted or plain finishes are the indoor-only option.
2) Will the B281SQHDG work on single-piece 1-5/8 inch strut instead of square post?
No. This base is dimensioned for B22A, B and C square post channel, which is the back-to-back closed profile, not a single run of standard strut. For a single channel run you need a flat post base sized for that profile instead.
3) What size footprint do I need to leave for a B281SQHDG square post base?
Plan on a 6 x 6 inch bearing area, with the fitting standing 3.5 inches tall from the mounting surface. It weighs 4 lb. If you are laying out anchors on a concrete pad or a roof curb, that 6 inch square is the plate you are drilling through.
4) Does the B281SQHDG post base come with anchors or bolts?
The B281SQHDG ships as the galvanized steel base fitting only. Concrete anchors, through bolts or the hardware attaching the post to the base are ordered separately and should be selected for the substrate and to match the galvanized finish so you are not mixing coatings in an exterior run.
5) What is the difference between a centered square post base and an offset one?
A centered base puts the post in the middle of the plate, so anchor loads spread evenly around it. That is what the B281SQHDG does. An offset or edge base shifts the post to one side of the plate, which you use when the post has to sit tight to a wall, a curb edge or an existing penetration. If you have clear pad on all sides, centered is the straightforward choice.
6) What is the correct part number to order this B-Line galvanized square post base?
Order it as B-Line B281SQHDG. The HDG suffix is the hot-dipped galvanized finish; the same base body is catalogued in other finishes under the B281SQ designation with a different suffix.
