Ives MB1P – Frequently Asked Questions

1) What is the Ives MB1/MB2 bracket actually for?
The MB1 and MB2 are aluminum mounting brackets that let you mount stop-mounted hardware over an Ives COR coordinator without damaging it. A coordinator sits on the stop of the inactive leaf, and anything else that wants that same stop (a parallel arm closer shoe, a surface vertical rod strike) has nowhere to land. The bracket carries that hardware and drops it to compensate for the height of the coordinator and the bracket itself, so the coordinator still swings the inactive leaf closed first. It is a mounting accessory, not a coordinator, so you order it in addition to the COR unit.
2) Can I use an Ives MB1 or MB2 bracket with a surface vertical rod strike on a fire rated pair?
No. The MB1/MB2 brackets accommodate parallel arm closers and non-fire-rated surface vertical rod strikes. If the pair is fire rated and you are mounting a top strike for a surface vertical rod device, this bracket is not the part for that opening. On non-rated pairs it is the correct way to get that strike mounted clear of the coordinator.
3) My parallel arm closer will not sit flat because the coordinator is in the way. What do I need?
That is the exact condition the Ives MB1/MB2 brackets solve. The coordinator occupies the stop across the head of the pair, and a parallel arm closer needs that same surface for its shoe. The bracket mounts over the coordinator and carries the closer shoe, lowered to make up for the height the coordinator and bracket add. Order the bracket in addition to the closer and the COR coordinator; it does not replace either.
4) What is the difference between the Ives MB1 and the MB2 mounting bracket?
MB1 and MB2 are the two bracket sizes offered under the same model designation, and you pick one per piece of stop-mounted hardware you are mounting over the coordinator. Both are aluminum and both come in three finishes: 711 Black Anodized, 689 Aluminum Painted, and 600 Primer Paint. When ordering, the bracket choice and the finish are two separate calls, so a black anodized MB2 orders as MB2-BLK and a primed MB1 as MB1P.
5) Does the Ives MB1/MB2 bracket meet ANSI A156.3?
Yes, the MB1/MB2 brackets are built to ANSI A156.3 Type 21A, which is the coordinator classification under the exit device and coordinator standard. That is the line a spec writer or facility procurement group is usually looking for when a door coordinator assembly has to be called out on a hardware schedule for a commercial opening.
6) Will the Ives MB1/MB2 bracket work with any brand of door coordinator?
The MB1 and MB2 are made for the Ives COR coordinator series and are sized to that hardware. If the coordinator already on your opening is another manufacturer's, the bracket is not a stated fit for it. On a retrofit, the clean route is to pair the bracket with a COR coordinator so the height stack is the one the bracket was made around.
7) Do I need one Ives mounting bracket or two for a pair of doors?
Count the pieces of stop-mounted hardware, not the leaves. Each MB1 or MB2 carries one item over the coordinator, so a pair with a parallel arm closer on each leaf plus the coordinator needs a bracket per closer. Openings with a single stop-mounted closer or one surface vertical rod strike over the coordinator need one. The brackets are ordered individually by size and finish, so you can mix an MB1 and an MB2 on the same opening if the hardware calls for it.
8) Which finish of Ives mounting bracket should I order to match my existing door hardware?
Three finishes are available across both bracket sizes. 711 Black Anodized suits dark frames and dark closer covers. 689 Aluminum Painted is the standard aluminum-look finish that matches most commercial closers and coordinators. 600 Primer Paint is meant to be field painted, which is the one to order when the frames in your building are painted to a custom color and you want the bracket to disappear into them. Since the bracket sits on the stop where it is visible above the doors, the finish call matters on a lobby or corridor opening.
