Don-Jo 3323-630 – Frequently Asked Questions

1) Will the Don-Jo 3323 overhead stop work on my 36 inch door?
That is exactly what the 3323 is sized for. It covers frame openings from 32 inches to 35-15/16 inches, which is the range a standard 36 inch commercial door leaf sits in. If your frame opening measures under 32 inches or over 35-15/16 inches, you need a different size in the family, not this one.
2) Do I need to order the Don-Jo 3323 surface overhead stop left or right handed?
No handing to specify. The 3323 is non-handed, so one part covers both left and right hand openings. For a property manager or facilities buyer standardizing across a building, that means a single line item stocks every 36 inch door regardless of swing.
3) Can I use a surface overhead stop on a fire rated door?
The Don-Jo 3323 is UL listed for use up to 90 minutes on wood fire doors and up to 3 hours on metal fire doors, so it can go on a fire rated assembly within those limits. It also meets ANSI AI56.3 C02541. Confirm your opening's required rating first: a wood door carrying a rating above 90 minutes is outside what this stop is listed for.
4) How far will the Don-Jo 3323 let the door open before it stops?
Standard installation sets the stop between 85 and 110 degrees of door opening. That gives some latitude to position the template where the wall, adjacent millwork, or an out-swinging neighbor door dictates, rather than being locked to one fixed angle.
5) Is this overhead stop a hold-open, or does it just stop the door?
The 3323 is a single-acting stop. It arrests the door at the set opening angle and gives consistent, controlled stopping, but it is the stop function rather than a hold-open arm. If you need the door to stay parked open, you are looking for a hold-open version of an overhead unit, not this one.
6) Why use an overhead stop instead of a wall or floor mounted door stop?
A surface overhead stop mounts on the door face and frame soffit, so nothing sits on the floor to trip over or collect dirt, and you are not relying on blocking in a wall that may not be there. It also controls the door at the top rail where the leverage is, which matters on heavy commercial doors. Wall and floor bumpers are simpler and cheaper, but they only work when there is a solid wall at the right spot or a floor you are willing to drill.
7) Is the Don-Jo 3323 rated for high traffic commercial openings?
It carries a heavy duty rating and is classified for commercial use, built in stainless steel throughout. That puts it in range for school corridors, hospital wings, retail entries, and warehouse openings where a light duty stop would get bent on the first hard swing.
8) What finish does the Don-Jo 3323 overhead stop come in?
One finish only: 630 satin stainless steel. It is the common commercial spec finish and matches satin stainless hinges, push plates, and exit device trim already on most institutional openings, so it drops into an existing hardware schedule without standing out.
