Don-Jo CSPB30 – Frequently Asked Questions

1) What is a Don-Jo CSPB 30 spreader bar actually used for on a commercial door frame?
The CSPB 30 is a steel bar used as a spacing and filler element in commercial door hardware installs, holding a set dimension where a rigid spacer is needed. It measures 36 inches long with a 3/4 inch width and 3/4 inch height, so it delivers a fixed 3/4 inch spacing across a 36 inch span. It is a commercial-duty component, not a residential trim piece.
2) Will a 36 inch Don-Jo spreader bar work on a 32 inch or 30 inch wide opening?
Not as supplied. The CSPB 30 is manufactured at a fixed 36 inch length, so on a narrower opening it either has to be cut down on site or you need a shorter bar. If you want the spacing dimension to be factory-accurate, size the bar to the opening rather than trimming it.
3) Does the Don-Jo CSPB 30 come as a single piece or do I have to buy a box?
It is packed as a shelf pack of 50 units, which is how Don-Jo lists it for contractors and distributors stocking multiple installs. Plan quantities in that pack size rather than by the single piece.
4) Is the Don-Jo CSPB 30 the same thing as a filler plate?
No. A filler plate covers an unused or oversized cutout in a door or frame; the CSPB 30 is a 3/4 by 3/4 inch steel bar 36 inches long that maintains spacing between two members. Don-Jo groups both under the same door trim accessory family, but if you are closing up an old lock prep or strike cutout you want a filler plate, not a spreader bar.
5) Is the Don-Jo CSPB 30 spreader bar finished or is it bare steel?
The substrate is steel and the model is specified by dimension and gauge rather than by a finish option. There is one configuration of the CSPB 30, so you are not choosing a finish at the order stage. If the bar will be exposed in a corrosive or wash-down area, plan on field coating it.
6) Is this Don-Jo bar heavy enough for a school or hospital corridor door?
It is built for that kind of traffic. Don-Jo specs the CSPB as commercial-grade, 16-gauge (0.060 inch) steel, and calls out educational, healthcare, office, retail, industrial and government facilities as typical applications. For a facility standardizing hardware across many openings, the fixed 36 inch by 3/4 by 3/4 inch dimension keeps every install identical.
