Don-Jo 2021-313 – Frequently Asked Questions

1) What size door opening does the Don-Jo 2021 door coordinator fit?
The 2021 covers frame openings from 56-1/16 inches up to 72 inches. The coordinator bar itself is 1-5/8 x 52 inches, so on anything wider than the bar it won't span the full header, and Don-Jo offers a filler bar to close out the remaining length for a finished look. Measure the frame opening, not the door leaf width, when you size it.
2) What does a door coordinator actually do on a pair of doors, and do I need one?
On a pair of doors with an overlapping astragal, the inactive leaf has to close before the active one or the doors bind and never latch. A coordinator like the Don-Jo 2021 holds the active leaf open until the inactive leaf has closed, then releases it so they latch in the right order. If your pair has no astragal and no overlap, or the two leaves are independent, you don't need one. If both leaves are on closers and you're getting doors that stand ajar or catch on each other, that's exactly what this solves.
3) Is the Don-Jo 2021 coordinator ANSI rated?
It conforms to ANSI A156.3 Type 21. Type 21 is the coordinator designation in that standard, so if your spec sheet or door schedule calls for an A156.3 Type 21 coordinator, the 2021 answers it directly. That matters most on institutional and government work where the hardware schedule names the standard rather than a brand.
4) Do I need anything else besides the coordinator to finish the install?
Two accessories decide the job. A filler bar if the 52 inch coordinator body doesn't run the full width of your header opening, which it won't on wider frames toward the 72 inch end. And mounting brackets, which Don-Jo offers to suit different frame configurations. Both are ordered separately from the 2021 itself. Also account for the closers and any surface strikes or hold-open hardware already mounted on the header, since the bar occupies that face.
5) My frame opening is under 56 inches. Can I still use the Don-Jo 2021?
No. The 2021 is sized for openings of 56-1/16 inches and up, to a maximum of 72 inches. Below that you need a shorter coordinator. The Ives COR Series is offered in a range of bar lengths, and the Trimco 3094 is stop mounted rather than sized to the full header, so either is worth pricing for a narrower pair.
6) What is an equivalent bar-type door coordinator to the Don-Jo 2021 that is UL listed for fire doors?
The Don-Jo 2021 is a bar-type coordinator in aluminum for frame openings 56-1/16 inch to 72 inch. For a fire door pair, the Ives COR aluminum bar coordinators are UL listed and fire rated, and the ABH 3700 Series full bar coordinator is UL listed and fire door compatible and includes a filler bar. All three sequence a pair of doors from a header-mounted bar, so the mounting approach on the frame soffit is the same; choose the UL listed peer where the opening carries a fire label.
7) What can I use instead of a bar coordinator when the header will not take a full-width bar?
The Don-Jo 2021 is a bar coordinator that mounts across the frame header and occupies 52 inches of soffit. Where that run of header is not available, the Trimco 3092 is a retracting arm coordinator and the Trimco 3094 is a stop mounted coordinator, both UL. The arm and stop mounted types sequence the pair from a shorter footprint rather than a bar spanning the opening, so they suit headers with obstructions or existing hardware in the way.
8) What finishes does the Don-Jo 2021 door coordinator come in?
Two: 313 dark brown aluminum and PC prime coated. Prime coated is the one to order when the header is getting painted to match the frame, since it takes finish paint directly. The 313 dark brown is a finished anodized look for bronze-toned frames. Both are on the same aluminum body.
9) What is the safety override on a door coordinator for?
It lets the active leaf close past the coordinator when heavy force is applied, instead of the mechanism jamming the opening. In an egress situation, or when someone shoves the active door hard, you want the door to move rather than the coordinator to hold it. The Don-Jo 2021 has that override built in, so it isn't a separate part to order.
10) Bar coordinator or gravity coordinator, which should I use?
A bar type like the Don-Jo 2021 runs across the frame header and is the common choice on standard pairs where you have clear header face to mount to. A gravity coordinator, such as the Ives COR7G or COR9G in brass with field adjustable operation, works differently and is the one to look at when the header is crowded or you want to tune the sequencing on site. Trimco also splits the difference two ways: the 3092 is a retracting arm coordinator and the 3094 is stop mounted, both useful when a full length bar across the header isn't practical.
11) Is the Don-Jo 2021 coordinator heavy duty enough for a school corridor or hospital pair?
It's built as commercial grade hardware, aluminum bodied, and meets ANSI A156.3 Type 21. That's the category used on office entries, school corridors, healthcare and government openings. It is not a residential part. One thing to settle separately: if the pair is a fire rated assembly, check whether your schedule requires a UL listed coordinator, because that listing is a distinct requirement from the A156.3 type designation.
12) Can I use one Don-Jo 2021 to standardize the double doors across my whole building?
Only where the frame openings land between 56-1/16 and 72 inches. That's a wide band and covers most standard commercial pairs, so one part number often does cover a floor or a wing. Openings outside that range need a different size, and any pair with a crowded header may need a stop mounted or gravity type instead. Walk the building and record frame opening widths before you commit to a single SKU across the fleet.
13) The coordinator bar does not fill my whole header opening. What coordinator comes with a filler bar?
The Don-Jo 2021 bar measures 1-5/8 inch by 52 inch while covering frame openings from 56-1/16 inch to 72 inch, so on the wider openings the bar is shorter than the header and an optional filler bar closes the gap. If you prefer the filler bar supplied with the coordinator rather than ordered separately, the ABH 3700 Series is a full bar coordinator that includes a filler bar.
14) Is there a coordinator that can be adjusted in the field after it is installed?
The Don-Jo 2021 is an aluminum bar coordinator with a built-in safety override that lets the active door close first under extreme force. If you want the sequencing behavior itself adjustable after mounting, the Ives COR7G and COR9G are brass gravity coordinators with field-adjustable operation and are fire rated. Gravity type coordinators work on a different principle than the spring-loaded bar, so confirm the opening suits a gravity unit before swapping.
15) Is a stop mounted coordinator the same thing as the Don-Jo 2021?
No. The Don-Jo 2021 is a bar coordinator, 1-5/8 inch by 52 inch, that spans the frame header and covers openings from 56-1/16 inch to 72 inch as a single unit sized to the opening. The Trimco 3094 is a stop mounted coordinator, which attaches at the door stop rather than running the width of the header, so the prep, the mounting location and the way it is sized to the opening all differ. They are not drop-in replacements for each other on an existing prep.
16) What is the difference between an aluminum bar coordinator and a brass gravity coordinator?
The Don-Jo 2021 is an aluminum bar coordinator finished in 628 aluminum, also offered in 313 dark brown aluminum and prime coated, and it holds the inactive door until the active leaf clears. The Ives COR7G and COR9G are brass gravity coordinators with field-adjustable operation and a fire rating. The material and the actuating principle differ, so the header prep and the finish match to the rest of the opening hardware are the two things to check before substituting one for the other.
