Stanley Security QRM111 8 689 – Frequently Asked Questions

1) Can I use a Stanley QRM111 mullion with rim exit devices on a pair of doors?
That is exactly what it is for. The QRM111 is a Grade 1 commercial mullion that stands between a pair of doors so each leaf can carry a rim exit device and latch into the mullion instead of into the other door. It comes pre-prepped for Stanley QED100 and QED300 Series rim devices, so the strike prep is already there for those.
2) What height openings will the QRM111 mullion cover?
Eight feet is the standard, and it is field-sizeable for taller openings. Orderable lengths run 8, 9, 10, 11 and 12 feet, so a 10-foot storefront pair or a 12-foot institutional opening is covered without a special order.
3) Do I need the keyed removable version of the QRM111, or is the fixed one fine?
Depends on whether the opening ever has to pass something wide. Keyed removable lets you unlock and lift the mullion out to clear the full width for moving furniture, equipment or gurneys, then drop it back in. If the pair is a plain egress door that never needs a clear opening, the non-keyed version is simpler and there is no cylinder to key. Both are offered in every length from 8 to 12 feet.
4) Which mullion should I use on a fire-rated 8 foot opening?
The Stanley QRM111 is a Grade 1 commercial mullion rated for openings up to 8 feet high, with its fire and hurricane rating applying at that 8 foot maximum height. That makes it the one to spec when a fire-rated pair with rim devices is at or under 8 feet. The Sargent 980 is a removable mullion supplied at an 86 inch standard height, so on a taller rated opening the Stanley is the one that covers the height.
5) Will a Sargent 980 mullion work with Stanley QED100 or QED300 exit devices?
Do not assume it drops in. The Stanley QRM111 is pre-prepped for mounting Stanley QED100 and QED300 series rim exit devices, so the strike and fastener prep is already there. The Sargent 980 is a removable mullion of its own series and is prepped to its maker's pattern. If the pair already carries QED100 or QED300 devices, the QRM111 is the mullion that matches the existing prep without field drilling.
6) What finishes does the QRM111 mullion come in, and can I paint it to match my frames?
Three: 689 aluminum painted (also called US28), 695 dark bronze painted, and 600 primed. The 600 primed option is the one to order when the mullion has to match a custom frame color, since it ships ready for the painter. All three are available in every length from 8 to 12 feet.
7) How heavy-duty is the QRM111 mullion tube for a high traffic entrance?
The tube is 2 by 3 inch steel with a 1/8 inch wall, and some variants use investment cast steel for the head caps, bottom sills and adapters. That is a Grade 1 commercial build, which is what you want on school, hospital and retail entrances where the mullion takes daily abuse from carts and crowds.
8) Is a removable mullion better than surface vertical rod devices on a pair of doors?
Different trade-off. With a mullion, both leaves get rim devices, which are simpler to install and maintain and have no rods to fall out of adjustment, and the QRM111 keyed removable version still lets you clear the whole opening when you need to. Surface vertical rods give you a clear opening all the time with no post in the middle, but they latch top and bottom and need more service. Mullions are usually the choice where traffic is heavy and maintenance budget is thin.
9) If I already have Stanley QED exit devices on the doors, do I need extra prep for this mullion?
No extra strike prep for QED100 or QED300 Series rim devices. The QRM111 comes pre-prepped for mounting those, so the device strikes land where they should. If the doors carry rim devices from another line, confirm the strike pattern before you cut anything.
10) Steel versus aluminum mullion - what is the difference between the Stanley QRM111 and the Sargent 980?
The Stanley QRM111 is built from a 2 inch by 3 inch steel mullion tube with a 1/8 inch wall, with investment cast steel head caps, bottom sills and adapters on some variants, and it is offered in 689 aluminum painted, 695 dark bronze painted and 600 primed for painting. The Sargent 980 is an extruded aluminum mullion in a T-shape profile. The 600 primed option on the Stanley is the one to specify when the mullion has to be finish-painted to match a frame color on site.
11) Do I need the keyed removable version of the Stanley QRM111, or is a plain removable mullion like the Sargent 980 enough?
Both the Sargent 980 and the Stanley QRM111 are removable mullions, so either can be taken out to move wide loads through the opening. The QRM111 is ordered with Keyed Removable as Yes or No across all four heights and all three finishes, so if you want removal restricted to a keyholder rather than anyone with access to the frame, choose the keyed removable option. If removal is only occasional and controlled by staff access, the non-keyed configuration covers it.
