Don-Jo SPB-30 – Frequently Asked Questions

1) What is a Don-Jo SPB 30 spreader bar actually used for on a commercial door?
The SPB 30 is a steel filler bar that fills the gap left in a door or frame, typically where an old lock, plate, or cutout leaves a void that needs to be closed off and squared up before trim goes over it. It is a 36 inch long bar with a 3/4 inch profile, so it spans a long opening rather than patching a single hole. Steel construction and a commercial rating put it in office, school, healthcare, retail, warehouse, multi-tenant and municipal work rather than residential door repair.
2) What size is the Don-Jo SPB 30 spreader bar, and will it cover a gap wider than 3/4 inch?
The SPB 30 measures 36 x 3/4 x 3/4 inches. That 3/4 inch section is the limit: it closes a void up to 3/4 inch across, and anything wider than that leaves an exposed edge no matter how you set the bar. For a wider void you want a flat filler or armor plate sized to the opening rather than a bar. Length is the flexible dimension, since 36 inches can be cut down on site.
3) How thick is the steel on the Don-Jo SPB 30 spreader bar?
16 gauge, which the manufacturer states as 0.060 inch. That is heavy enough to stay straight over a 36 inch run without oil-canning, which is the point of a spreader bar: it holds its line across the full span instead of following the waves in whatever it is filling against.
4) Does the Don-Jo SPB 30 come in any length other than 36 inches?
36 inches is the only length offered for the SPB 30. If your opening needs less, the bar is cut to suit; if it needs more, you are into multiple bars or a different part number in the Don-Jo filler range.
5) Is the Don-Jo SPB 30 spreader bar sold individually or in a case?
It ships in a shelf pack of 50 units. That suits a locksmith shop or a contractor standardizing filler work across a building, less so a buyer who needs one bar for one door.
6) Is a spreader bar the same thing as an armor plate or a kick plate?
No, and they solve different problems. A kick plate or armor plate is a flat sheet that covers a face of the door against abuse and impact. The SPB 30 is a bar with a 3/4 inch square profile that fills a void, so it works in the gap rather than over the surface. If the door face is getting beaten up by carts, you want a plate. If there is an open channel or cutout to close before finishing, the bar is the right part.
7) Can the Don-Jo SPB 30 spreader bar be painted to match existing door hardware?
It is bare steel, so it takes primer and paint the way any steel door component does. There is no plated or anodized finish to key over, which is normally what you want on a filler: it gets painted out to match the door or frame rather than showing as a separate finish.
