Trimco 3094 UL Stop Mounted Coordinator

The 3094 coordinator is ordered by the width of the pair of doors it sits over, in four ranges: 43 to 53 inches, 53 to 63 inches, 63 to 75 inches, and 75 to 87 inches. Measure the full opening across both leaves, frame rabbet to frame rabbet, and pick the range that contains it. Ordering by single leaf width is the usual mistake and it lands you a bar that will not span the opening.

A coordinator is only needed on a pair of doors with an overlapping astragal, or where an active leaf carries a mortise lock or vertical rod device that must latch into the inactive leaf. The 3094 is a stop mounted bar that holds the active leaf open until the inactive leaf has closed, then releases it so both latch in the right order. On a pair with no astragal and no dependency between leaves, you do not need a coordinator at all. It is a commercial device, not residential hardware.

The 3094 needs low closing force to function. A coordinator holds the active leaf against the closer's own spring while the inactive leaf closes, so if the closers are cranked to a high spring size or the sweep speed is set fast, the coordinator gets overpowered and the doors close out of sequence. Plan on setting the closers to the lowest size that still closes and latches the door. This is also why it works alongside ADA compliant opening force requirements rather than fighting them.

The ABH 3700 Series full bar door coordinator is the closest like-for-like swap. Like the Trimco 3094, it is a bar-type coordinator furnished with a filler bar and is UL listed for fire door use, so it sequences the inactive and active leaves on a pair the same way. The Trimco 3094 is stop mounted and supplied in a paintable matte black with an oversized filler bar; the ABH 3700 carries its own filler bar arrangement. Both are specified by the width of the opening they have to span, so confirm the door opening range before ordering either.

A bar type unit such as the Trimco 3094 mounts on the stop and runs a bar across the full width of the opening, holding the inactive leaf until the active leaf clears; it is furnished with an oversized filler bar and is engineered to reduce operating noise, and it requires low closing force to work properly. The Ives COR7G/COR9G is a brass gravity coordinator with field-adjustable operation and is fire rated. The gravity design works off the movement of the leaves rather than a full-width bar, which changes what has to be mounted across the head of the frame. Both approaches are used on fire rated pairs, so the choice comes down to how the head of the frame is prepped and how much adjustment you want in the field.

The Trimco 3094 covers door openings from 43 inches up to 87 inches, in four spans: 43 to 53, 53 to 63, 63 to 75, and 75 to 87 inches. For an opening outside that, look at the Ives COR Series aluminum bar coordinators, which are UL listed and fire rated and are offered as a family of lengths across the COR32, COR42, COR52, COR60 and COR72 sizes. Measure the clear opening of the pair, not the leaf width, and match it to the coordinator span.

A full bar unit will not suit that opening. The Trimco 3094 is a stop mounted coordinator furnished complete with an oversized filler bar, and the ABH 3700 Series is likewise a full bar coordinator with a filler bar. For a head that cannot take a bar across the opening, the Ives COR7G/COR9G brass gravity coordinator is the alternative, and it is fire rated so it can still go on a rated pair.

The 3094 has an adjustable override built in. If the leaves are forced out of sequence, the override lets the arm give way instead of transferring the load into the hinges, so you do not end up with racked hinges or a bent door and frame. On high traffic openings where the public will push both leaves at once, that adjustment is the setting worth spending time on during install.

No, an oversized filler bar comes with the 3094. The filler bar spans the rest of the frame soffit beside the coordinator body so the mounted assembly runs the full width of the opening and gives you continuous mounting for closer brackets and hold open arms. Oversized means it can be cut down on site to suit the exact frame, so one part covers a range of openings.

The 3094 is ADA compliant. That matters because a coordinator sits in the closing cycle, not the opening cycle, so it does not add to the push force a person feels on the way in. What it does require is that the closers be set to low closing force, which pulls in the same direction as the ADA force limits rather than against them.

The Trimco 3094 has an adjustable override that prevents racking hinges or damage to the door and frame, so the override force can be set once the pair is hung. If you want adjustment in the operation itself, the Ives COR7G/COR9G is a brass gravity coordinator described as field adjustable, and it is fire rated. On a pair that is being commissioned with closers still being tuned, the ability to adjust on site matters, because the Trimco 3094 is designed around a low closing force and the closers have to be set to suit.

They do the same job but they are not identical parts. The Ives COR Series is an aluminum bar coordinator and is UL listed and fire rated. The Trimco 3094 is a stop mounted bar coordinator finished in a paintable matte black, and is also offered in silver, with an oversized filler bar included. If the specification calls out a finish to be painted to match the frame, the paintable matte black of the 3094 is the relevant difference; if the drawing calls out a specific Ives COR size, substitute only after matching the opening width.

The Trimco 3094 is ADA compliant and specified for commercial use. It is built around a low closing force, which is the same constraint ADA opening force puts on the closers of the pair. The ABH 3700 Series and the Ives COR Series are both UL listed for fire door use, and the Ives COR7G/COR9G gravity coordinator is fire rated as well. Whichever coordinator goes on the head, the opening force still has to be verified at the door after the closers are adjusted, because the coordinator adds resistance to the sequence.

Yes, by staying in one series and changing the span. The Trimco 3094 is a single series that runs from 43 to 87 inch openings across four spans, in black and in silver, so a facility with varied pair widths can carry one part family and one finish scheme. The Ives COR Series is similarly built as a family of aluminum bar coordinators across the COR32, COR42, COR52, COR60 and COR72 sizes, and the ABH 3700 Series is another full bar family. Standardizing on one series keeps the mounting and the adjustment procedure the same for maintenance staff across every pair.

Noise was engineered down on the 3094 specifically. Older bar coordinators tend to slap when the trigger releases the active leaf, which is a real complaint in hospitals, hotels, dorms and any corridor pair near occupied rooms. If a quiet corridor is the priority, that release behavior is the reason to pick this one.

Two finishes are offered, black and silver. The black is a paintable matte black, so if the frames are a custom color you can shoot it to match rather than living with a contrasting bar across the head. Silver is the choice where the frames are aluminum or a brushed alloy.
