3094 Series Stop Mounted Coordinator
- The 3094 Stop Mounted Door Coordinators are designed to give extremely high-end reliability, low friction and low-noise performance at a moderate price. Fully automatic, the 3094 Stop-Mounted Coordinators are used to sequence pairs of doors where one leaf must close before the other. Featuring black nylon-coated triggers and rollers stops, two “quiet” rollers, and internal rubber shock absorbers, the 3094 Series requires less closing force and greatly reduces noises to the lowest levels possible. Engineered for use with equal or unequal pairs of doors and with an adjustable override feature to prevent damage to the doors, coordinator, frame and hinges in the event the active leaf is forced to close, Trimco’s 3094 Series is the most flexible and durable coordinator on the market.

Trimco TRI-3094B4.BLACK – Frequently Asked Questions
1) What size opening does the Trimco 3094 C4/B4 coordinator cover?
Two opening ranges are covered: 87 to 95 inches and 95 to 107 inches. Those correspond to the 3094B4 (52 inch coordinator with filler bar, 87 to 95 inch openings) and the 3094C4 (60 inch coordinator with filler bar, 95 to 107 inch openings). Measure the full opening width of the pair, frame rabbet to frame rabbet, and pick the range it lands in. If your opening is narrower, the same 3094 Series runs down through 3094A2 for 43 to 53 inch openings, 3094B1 for 53 to 64, 3094B2 for 63 to 75, and 3094B3 for 75 to 87.
2) Do I need a coordinator on my pair of doors, or will closers alone do it?
A coordinator is what you add when one leaf has to close before the other, which is the case on a pair with an overlapping astragal or a pair carrying a vertical rod device where the inactive leaf must land first. Closers on their own do not sequence the leaves, so the active leaf can beat the inactive one and leave the pair unlatched. The 3094 stop mounted coordinator is fully automatic, so it holds the active leaf open until the inactive leaf has closed and then releases it. On a pair with no astragal and no sequencing requirement, you do not need one.
3) Will the Trimco 3094 coordinator work on an unequal pair of doors?
Yes, the 3094 Series is engineered for equal or unequal pairs. That matters because unequal pairs are common where one leaf is a 36 inch active leaf and the other is a narrower inactive leaf, and the coordinator still has to trigger off the inactive leaf. Pick the model by the total opening width, not by the individual leaf widths.
4) What mounting bracket do I need for a Trimco 3094 coordinator, and how do I pick between the 3095 and 3096?
Pick the bracket off the width of the frame stop. The 3095 bracket covers stop widths from 7/8 inch to 2-1/4 inch and measures 3-1/4 x 5 inches overall. The 3096 bracket covers stop widths over 2-1/4 inch and measures 3 x 5 inches overall. Measure the stop on your existing frame before ordering, because the coordinator mounts to the stop and the wrong bracket will not sit on it.
5) Will a coordinator keep someone from pushing the active door shut first and racking the hinges?
That is the failure a coordinator normally causes, and the 3094 has an adjustable override built in specifically for it. If the active leaf is forced closed ahead of the inactive one, the override gives way instead of transmitting the load into the door, the coordinator, the frame, or the hinges. The housing tube also cannot be crushed into a condition where it stops operating. On heavy-traffic openings in schools or multifamily corridors, that is what keeps the coordinator from becoming a callback.
6) What is the closest equivalent to a Trimco 3094 stop mounted coordinator on a UL listed fire door pair?
The ABH 3700 Series full bar door coordinator ships with a filler bar and is UL listed for fire door use, which makes it the nearest like for like swap for a 3094 on a labeled pair. Both are bar type coordinators mounted at the stop and both come complete with filler bar, so the sequencing behavior on an unequal pair is the same. The Trimco 3094 covers openings up to 107 inches across its size range and is finished in a paintable matte black, with silver also offered.
7) What coordinator should I use instead of a bar type when the pair has a very wide stop or no room for a full bar across the head?
Look at the Ives COR7G and COR9G brass gravity coordinator, which is UL fire rated and is field adjustable in operation. A gravity coordinator works off the leaf itself rather than a bar running the width of the opening, so it suits heads where a full length bar will not lay in. The Trimco 3094 is the bar approach: it is furnished complete with an oversized filler bar and uses the 3095 bracket for stop widths of 7/8 inch to 2-1/4 inch and the 3096 bracket for stops over 2-1/4 inch.
8) Is the Ives COR series aluminum bar coordinator a direct substitute for a Trimco 3094?
It is the same class of part. The Ives COR32/42/52/60/72 aluminum bar coordinators are UL listed and fire rated, and like the 3094 they sequence a pair so the inactive leaf closes first. The difference is construction: the Ives bars are aluminum, while the 3094 runs black nylon coated triggers and roller stops with two quiet rollers and internal rubber shock absorbers, and carries an adjustable override to prevent racking the hinges if the active leaf is forced closed. Confirm the opening width falls in the size you need before swapping either way.
9) Is a filler bar included with the Trimco 3094 coordinator or do I order it separately?
It comes furnished complete with an oversized filler bar, so you are not adding a line item to cover the rest of the opening. If a job needs a different length, the 3094 filler bars are sold individually in 12 inch (3094-1), 24 inch (3094-2), 36 inch (3094-3), 48 inch (3094-4), and 60 inch (3094-5). The mounting brackets, 3095 or 3096, are separate.
10) Is the Trimco 3094 stop mounted coordinator quiet enough for a hotel or apartment corridor?
Noise is what this one is built around. The triggers and roller stops are black nylon coated, there are two quiet rollers, and internal rubber shock absorbers take the impact, so operating noise is held down compared to a bare metal coordinator. It also requires low closing force, which means the closers do not have to be cranked up to overcome it. Hospitality and multifamily or mixed-use are named applications, along with commercial and industrial buildings, office buildings, and schools.
11) Is the Trimco 3094 coordinator ADA compliant and suitable for commercial openings?
The 3094 is ADA compliant and is a commercial-duty product, not a residential one. The ADA side of a pair of doors usually comes down to opening force, and the low closing force this coordinator requires means it adds less resistance for the closers to fight, which is the part that tends to push a pair out of compliance.
12) What is the difference between a bar type coordinator and a gravity coordinator?
A bar type coordinator like the Trimco 3094 mounts on the frame stop and spans the opening, with a trigger arm on the inactive leaf holding the active leaf back until the inactive one closes. ZenSupply also carries the Ives COR7G/COR9G brass gravity coordinator with field-adjustable operation, which works off a pivoting gravity arm instead of a full-width bar. The bar type runs across the head so it needs the filler bar and a stop it can mount to; the gravity type takes up less of the head but is a different install entirely. If you want the same full-bar approach from another brand, the ABH 3700 Series full bar coordinator with filler bar and the Ives COR Series aluminum bar coordinators are both bar type.
13) I need a coordinator on a fire rated pair of doors. What are my options?
For fire rated pairs, ZenSupply carries the Ives COR Series aluminum bar coordinators and the Ives COR7G/COR9G brass gravity coordinator, both of which we hold a fire rating on, and the ABH 3700 Series full bar coordinator with filler bar, which is UL Listed and fire door compatible. On a fire rated pair the coordinator is part of the listed assembly, so match it to what the door and frame labels permit.
14) What is the closest substitute for a Trimco 3094 if I want a full bar coordinator from a different brand?
The ABH 3700 Series full bar door coordinator with filler bar is the straight like-for-like: same full-bar format, supplied with a filler bar the way the 3094 is. The Ives COR Series aluminum bar coordinators are the other bar type option we stock. Both are a different mounting template than the Trimco, so if you are replacing an existing 3094 on an in-service frame and want to reuse the existing holes, stay with the 3094 Series and size it by opening width.
15) Which coordinator is simpler to set up in the field on a retrofit pair?
The Ives COR7G and COR9G brass gravity coordinators are field adjustable in operation, which is the simpler path when you are fitting an existing pair and want to tune the sequence on site. The Trimco 3094 is sized to the opening at order time, in bands that run 43 to 53 inches, 53 to 64 inches, 63 to 75 inches, 75 to 87 inches, 87 to 95 inches and 95 to 107 inches, and it also carries an adjustable override so a forced active leaf does not damage the door, frame or coordinator.
16) For a commercial pair that has to meet ADA, which of these coordinators fit?
The Trimco 3094 is rated ADA compliant and specified for commercial use, and it is engineered to require low closing force, which is what matters when the pair also has to open within an accessible force limit. Among the alternatives, the ABH 3700 Series is UL listed and fire door compatible, and the Ives COR aluminum bar and COR7G/COR9G brass gravity coordinators are both fire rated, so all three suit labeled openings in schools, hospitality, office and multifamily work.
17) I need a coordinator for an opening wider than 107 inches - what are my options?
The standard Trimco 3094 sizes stop at the 3094C4, a 60 inch coordinator with filler bar covering openings 95 inches to 107 inches; beyond that the 3094D is the custom size and special application version. If you would rather stay with a catalog size, the Ives COR series runs COR32, COR42, COR52, COR60 and COR72 aluminum bar coordinators, all UL listed and fire rated, so there is a longer bar to select from.
18) Will a door closer or a gravity coordinator do the same job as the 3094?
No. A coordinator is the part that sequences a pair so the inactive leaf closes before the active one, and the Trimco 3094 does that fully automatically on equal or unequal pairs. A closer only controls one leaf and will not hold the sequence. If you want a coordinator that works by a different mechanism, that is the Ives COR7G or COR9G brass gravity coordinator, which is fire rated and field adjustable - still a coordinator, just not a bar across the head like the 3094 or the ABH 3700 Series full bar unit.
19) What finishes does the Trimco 3094 C4/B4 coordinator come in, and can I paint it to match the frame?
Black and silver are the two finishes offered, in both the 87 to 95 inch and 95 to 107 inch opening sizes. The matte black is paintable, so on a frame that has been finish-painted a color you can shoot the coordinator to match rather than leaving a black bar across the head.
20) My opening is an odd width and nothing in the standard 3094 range matches. What then?
Trimco lists the 3094D for custom sizes or special applications, coordinator with filler bar. That is the route for an opening that falls outside the standard breaks, or for a special condition the stock sizes do not cover. For anything inside the normal range, the standard models run from 43 inch openings up to 107 inches.
21) If noise on the pair is the complaint, which coordinator addresses it?
The Trimco 3094 is the one built around it: black nylon coated triggers and roller stops, two quiet rollers and internal rubber shock absorbers, engineered to greatly reduce operating noise and to require less closing force. The ABH 3700 Series full bar coordinator and the Ives COR aluminum bar coordinators are both fire rated bar coordinators that will sequence the same pair, so choose on construction and opening size if noise is not the deciding factor.
