Don-Jo 3123-630 – Frequently Asked Questions

1) Is the Don-Jo 3123 overhead stop handed, or will one part work on both left- and right-hand doors?
The Don-Jo 3123 surface overhead stop is non-handed, so the same part works on a left-hand or right-hand opening. For a property manager or maintenance shop stocking overhead stops across a building, that means one part number on the shelf instead of a left and a right, and no handing to get wrong on the purchase order.
2) Can I use the Don-Jo 3123 overhead stop on a double-acting door that swings both ways?
No. The 3123 is built for single-acting interior doors, the kind that swing one direction only. On a double-acting door it is the wrong part, and you need a stop rated for double-acting service instead. Check which way the leaf swings before you order.
3) Does installing a Don-Jo 3123 overhead stop require mortising the door or the frame?
No mortising. The 3123 is a surface-mounted overhead stop: the track mounts to the face of the door and the arm bracket to the frame (or head soffit), so there is no routing or pocket prep required. That is the practical reason to pick a surface stop over a concealed one on a retrofit, where you are working on a door that is already hung and painted and you do not want to pull it to mill it.
4) Does the Don-Jo 3123 overhead stop meet ANSI A156.3?
Yes, it is compliant with ANSI A156.3 C05541, the standard covering exit devices and overhead stops and holders. If a facility spec or a hardware schedule calls out an A156.3 C05541 overhead stop for a commercial interior opening, the 3123 answers that line. It is a commercial-rated product, not residential.
5) What finish does the Don-Jo 3123 overhead stop come in, and will it match my other door hardware?
One finish: 630, satin stainless steel. That is the most common commercial finish on levers, exit devices, push plates and hinges, so a 3123 will read as a match against most stainless or brushed chrome-look hardware already on the opening. If your building is standardized on a brass or bronze finish, this stop will stand out.
6) Do I still need a wall stop or floor stop if I install a Don-Jo 3123 overhead stop?
Usually not. An overhead stop like the 3123 stops the door at the head, so it does the job a wall or floor stop would, and it is the answer where there is no wall behind the door to catch it, where a floor stop would be a trip hazard, or where a glass wall or millwork sits in the swing path. It is also the choice when you want the stopping force taken through the frame rather than through a single anchor in drywall.
7) Is a Don-Jo 3123 overhead stop made of stainless steel, and will it hold up in a healthcare or food-service corridor?
The 3123 is stainless steel throughout, which is why it gets specified where doors get washed down or where humidity and cleaning chemicals would pit a plated steel stop. Hospitals, schools, retail back-of-house and multi-tenant residential corridors are the usual homes for it.
