Don-Jo 3324-630 – Frequently Asked Questions

1) Will the Don-Jo 3324 overhead stop work on a 42 inch wide door?
No. The 3324 is sized for a 36 inch door, and its stated compatibility runs 36 to 48 inches on butt-hung doors and 39 to 48 inches on center-hung doors, but the frame opening it fits is 42 inches to 43-15/16 inches. A 42 inch door leaf sits in a wider frame opening than that, so you need the size of the 3324 family built for that opening rather than this one. Match the stop to the frame opening measurement, not just the leaf width.
2) Can I use a surface overhead stop on a fire-rated door?
The Don-Jo 3324 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 rated assembly within those limits. It also complies with ANSI A156.3 C02541. If your opening is a wood door with a rating above 90 minutes, this stop is not the right part for it.
3) How far will the Don-Jo 3324 let the door open?
Standard installation of the 3324 gives a stop range from 85 to 110 degrees of door opening. It is a single-acting stop, so it arrests the leaf at that point in one direction. If you need the door to hold open rather than just stop, this is a stop only, not a hold-open.
4) Is the Don-Jo 3324 suitable for a center-hung door?
Yes, within limits. Center-hung compatibility on the 3324 runs 39 to 48 inches, versus 36 to 48 inches for butt-hung doors. So a 36 inch center-hung leaf falls below the range even though a 36 inch butt-hung leaf is covered.
5) Do I need to know the door handing before ordering the Don-Jo 3324?
No. The 3324 is non-handed, so one part covers left and right hand openings. That is useful if you are stocking stops for a building with mixed swings, since you carry one item instead of two.
6) Is a surface overhead stop better than a floor stop or a wall stop for a commercial corridor?
An overhead stop like the Don-Jo 3324 mounts on the door and frame head, so nothing sits in the floor to trip over or collect dirt, and you are not relying on a wall being in reach behind the leaf. That is why they get specified in healthcare, schools, and corridors where a floor stop is a hazard and there is no adjacent wall. A wall or floor stop is simpler and cheaper where the geometry allows it; the overhead stop is what you use when it doesn't.
7) Will the Don-Jo 3324 hold up on an exterior door?
Yes. The 3324 is stainless steel with a 630 satin stainless finish, rated for interior and exterior use, and classified heavy duty. 630 is the standard satin stainless finish code, so it matches other 630 hardware already on the opening.
8) Does the Don-Jo 3324 come in other finishes?
The 3324 is offered in one finish, 630 satin stainless steel. There is no other finish option on this model, so if the opening is specified in 626 chrome or a painted finish you will be matching to satin stainless or choosing a different stop.
