Eaton B280SQZN – Frequently Asked Questions

1) How much floor space does the Eaton B280SQZN post base need, and how tall does it sit the strut?
The base plate is 6 x 6 inches square and the fitting stands 3.5 inches tall, so a strut post set on it starts 3.5 inches above the deck. Lay out your anchor pattern and equipment clearances against that 6 inch square footprint, and add the 3.5 inches to any overall height you have to hit on the drawing.
2) Is the Eaton B-Line B280SQZN post base suitable for outdoor or wet locations?
It is steel with an electro-plated finish, which is a zinc plating meant for dry indoor service, mechanical rooms, plant interiors, and covered areas. For exterior work, roof curbs, parking structures, wash-down areas, or anywhere the base sits in standing water, specify a hot-dip galvanized or stainless post base instead. Electro-plate is a thin coating and it will not hold up to sustained weather exposure.
3) Does the Eaton B280SQZN post base come with anchors or channel bolts?
No. The B280SQZN is the post base casting alone, 3.92 lb of plated steel. You supply the concrete anchors or floor fasteners that hold the 6 x 6 inch plate down, and the channel nuts and bolts that tie the B22 strut into the base. Size the anchors to your deck material and load, and get the fasteners on the same order so the crew is not waiting on them.
4) Is a square post base like the B280SQZN the right choice, or should I use a channel bracket or floor flange instead?
A square post base is what you use when a strut run has to stand up off a floor or pad as a free-standing post, not hang off a wall or slab. The centered square post design puts the channel in the middle of a 6 x 6 inch plate so the load runs straight down the post into the deck. If your strut is running along a wall or under a slab, a channel bracket or a beam clamp is the correct part, not a base. If the post has to be offset from center for clearance, this centered version will not give you that.
5) What is the Eaton B-Line B280SQZN part number I should put on my order?
Order it as Eaton B-Line B280SQZN. That single catalog number covers the 3.5 inch square post base in steel with electro-plated finish for B22 channel. If your spec calls for a different finish, the suffix changes, so quote the number exactly as written to avoid getting a plated part where a galvanized one was specified.
6) Can I use the B280SQZN post base to stand up strut for HVAC units or electrical gear on a roof deck or equipment pad?
Indoors, yes. The base gives a 6 x 6 inch bearing plate and 3.5 inches of standoff for supporting mechanical equipment platforms, electrical gear, cable tray posts, and HVAC support frames built out of B22 channel. It is an electro-plated part, so keep it to interior pads and mechanical rooms. Roof-deck and exterior equipment supports want a galvanized base instead.
