Ives IVE-CB1-US26D – Frequently Asked Questions

1) What does the Ives CB1 carry bar coordinator actually do on a pair of doors?
The CB1 is a carry bar coordinator for pairs of doors with an overlapping astragal. It holds the inactive leaf open until the active leaf has closed past it, so the two doors always close in the right order. Without one, on a pair where someone pushes the inactive leaf shut first, the active leaf hits the astragal and the doors never latch, which chews up the astragal and the closer arms over time. A nylon roller on the bar carries the leaf, so the action is quiet. If both leaves are active and there is no astragal, you don't need a coordinator at all.
2) Do I need to specify handing for the Ives CB1 coordinator?
No handing to determine. The CB1 is non-handed, so one part covers either configuration and you can stock a single item across a building's pairs rather than a left and a right. Pick the finish and that is the whole order decision.
3) Is the Ives CB1 a bar-type or a frame-mounted coordinator, and where does it mount?
Carry bar type. The CB1 mounts on the frame soffit above the pair and carries the inactive leaf on a nylon roller, and it ships with through bolts for the mounting. Body size is 1-5/8" x 5-3/4"-2-1/2". That soffit space is the thing to check first: if the head is already crowded by a surface closer, overhead stop or magnetic holder, a stop-mounted coordinator like the Trimco 3094 sits differently at the head and may clear where a bar will not.
4) Is the Ives CB1 ANSI rated for a commercial spec job?
It meets ANSI A156.3 Type 21A and is classed as commercial-duty. Type 21A is the coordinator designation, so if the door schedule calls for an A156.3 Type 21A coordinator the CB1 answers that line directly. Steel body.
5) What is the closest equivalent to the Ives CB1 carry bar coordinator from another manufacturer?
The ABH 3700 Series is the nearest full bar coordinator to the Ives CB1. Both are bar-style coordinators that hold the inactive leaf of a pair until the active leaf closes, rather than arm-style units. The CB1 is a steel carry bar with a nylon roller measuring 1-5/8 inch by 5-3/4 inch to 2-1/2 inch and meets ANSI A156.3 Type 21A. The ABH 3700 Series is a full bar coordinator supplied with a filler bar and is UL listed for fire door use. If the opening is a labeled fire pair, the 3700 Series with its filler bar is the one specified for that condition; for a standard commercial pair, the CB1 carry bar covers the same coordinating job.
6) The frame soffit on my paired opening is crowded with other hardware - what coordinator can I use instead of a carry bar?
Look at the Trimco 3094, a stop mounted coordinator. It mounts to the door stop rather than spanning the frame head the way a bar coordinator does, which changes where the unit sits relative to closers, hold-opens and strikes on the soffit. The Ives CB1 is a carry bar coordinator, a steel bar with a nylon roller measuring 1-5/8 inch by 5-3/4 inch to 2-1/2 inch, and it needs a clear run across the head of the pair. The Trimco 3094 is UL rated. Confirm the mounting surface you actually have before choosing between the two - stop mounted and bar styles are not interchangeable in the field.
7) What is the difference between the Ives CB1 and the Trimco 3092 coordinator?
They coordinate a pair by different mechanisms. The Ives CB1 is a steel carry bar coordinator with a nylon roller, non-handed, meeting ANSI A156.3 Type 21A. The Trimco 3092 is a retracting arm coordinator and is UL rated. A bar coordinator carries the inactive leaf across the width of the opening; a retracting arm coordinator works through an arm that retracts as the active leaf closes. For a locksmith or hardware installer replacing an existing unit, this matters because the frame prep and mounting footprint follow the mechanism - a 3092 arm unit is not a drop-in for a CB1 carry bar or the reverse.
8) What finishes does the Ives CB1 coordinator come in?
Eight finishes: 600 primer paint, 631 matte black, 632 bright brass, 633 satin brass, 639 satin bronze, 640 satin bronze oil-rubbed, 651 bright chrome and 652 satin chrome. On most jobs the coordinator lives on the frame soffit where nobody sees it, so 600 primer (CB1-USP) is the practical pick when you intend to paint it to the frame. Match a BHMA number to the rest of the opening only if the head is visible.
9) Carry bar coordinator or a retracting arm coordinator, which should I use?
A carry bar like the CB1 runs a bar across the head with a nylon roller that holds the inactive leaf back, and it is non-handed, so it is the simple, low-decision choice on a standard pair. A retracting arm type such as the Trimco 3092 works with an arm that pulls back out of the way instead of a fixed bar across the opening, which is what people reach for when the head is congested or the look of a bar across the pair is a problem. The ABH 3700 is the full bar version with a filler bar for wider openings.
10) What else do I need to order with an Ives CB1 to finish a pair of doors?
Through bolts for mounting the coordinator come with it. What the CB1 does not include is the rest of the coordination package: the inactive leaf still needs flush bolts or a manual/automatic bolt to hold it, and each leaf needs its own closer for the coordinator to have anything to sequence. On a set with surface closers at the head, also confirm you have carry bar brackets or filler as the frame requires. The coordinator by itself only enforces closing order.
11) How wide an opening will one Ives CB1 coordinator cover?
The CB1 body is 1-5/8" x 5-3/4"-2-1/2" and it is sold as a single non-handed unit rather than in cut-to-width sizes. On unusually wide pairs where a coordinator has to span more frame than a standard body reaches, the ABH 3700 Series is the full bar type supplied with a filler bar to make up the run.
12) Can I standardize on the Ives CB1 across every pair of doors in my building?
For paired openings with an astragal, yes, and that is the main reason to pick it: one non-handed part number covers left and right configurations, so one line item on a PO covers the whole facility. Order the same finish across the board and the stockroom carries a single SKU. Openings that are fire rated with a listed coordinator called out in the hardware set are the exception, and pairs with no astragal do not need a coordinator at all.
13) I am standardizing coordinators across a facility with both labeled fire pairs and ordinary interior pairs. Do I need more than one model?
Plan on more than one. For labeled fire pairs, the ABH 3700 Series is a full bar coordinator that is UL listed for fire door use and ships with a filler bar; the Trimco 3092 retracting arm coordinator and Trimco 3094 stop mounted coordinator are both UL rated as well, which gives you an arm style and a stop mounted style for openings where a full bar will not fit. For ordinary commercial interior pairs, the Ives CB1 is a commercial-duty steel carry bar coordinator with a nylon roller meeting ANSI A156.3 Type 21A, and it is non-handed, so one part number covers both hands across the building. The CB1 also comes in eight finishes including 626-family satin chrome (652), satin brass (633) and primer paint (600), which helps match it to existing hardware across a mixed facility.
14) Is a full bar coordinator with a filler bar the same thing as the Ives CB1 carry bar?
No, and they order differently. The Ives CB1 is a fixed-size carry bar coordinator measuring 1-5/8 inch by 5-3/4 inch to 2-1/2 inch, so it goes on as a single non-handed part with the through bolts it includes. The ABH 3700 Series is a full bar coordinator supplied with a filler bar, meaning the bar assembly is made up to suit the width of the opening. On a standard-width pair the CB1 carry bar is the simpler part to specify and stock; on a wider pair, or where the opening width varies from door to door, the 3700 Series filler bar arrangement is what handles that range. The 3700 Series is also UL listed for fire door use.
15) Will an Ives CB1 hold up in a high traffic corridor, or will it wear out?
Steel body, commercial-rated, with a nylon roller as the wear surface where the leaf rides. Nylon on the contact point is what keeps it quiet and keeps steel off the astragal, so a school or hospital corridor pair is squarely what it is built for. The roller is the part that takes the cycles rather than the frame or the door edge.
