Sargent 12-980 GRAY 86 – Frequently Asked Questions

1) What does a removable mullion like the Sargent 12-980 actually do on a pair of doors?
A removable mullion is the vertical post 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 leaf. The Sargent 12-980 is the removable type, so it lifts out when you need the full clear opening for moving equipment or furniture, then drops back in and restores the latching point. That is the trade-off versus a fixed center post: same latching surface for rim devices, but you get the wide opening back when you need it.
2) Can I use the Sargent 12-980 mullion on a fire rated opening?
Yes. The 12-980 is a fire rated removable mullion and is ULC listed. It also works on non-rated openings, so a facility standardizing on one mullion across both rated and non-rated pairs can use the same part. On a rated opening, the exit devices mounted to the doors have to be fire rated as well, and the mullion must be in place and latched for the opening to perform as rated.
3) Do I need a mullion at all, or can I use vertical rod exit devices on my pair of doors?
Two ways to secure a pair. With a removable mullion like the Sargent 12-980, each leaf gets a rim device that latches into the post, which keeps the hardware simple and the latching positive at one point per leaf. With surface or concealed vertical rod devices you skip the post entirely, the doors latch at the head and the threshold, and the opening stays clear all the time. Choose the mullion when you want rim devices and a clean free-swinging pair most of the time but still need the full width occasionally; choose vertical rods when a post in the middle of the opening is unacceptable.
4) What is the closest alternative to the Sargent 12-980 removable mullion from another manufacturer?
The Stanley Security QRM111 is a Grade 1 mullion from the QRM100 Series and is the nearest peer for an opening where the Sargent 12-980 removable mullion would be specified. Both are removable-style mullion assemblies for pairs of doors fitted with exit devices. The Sargent 12-980 is steel with a gray prime coat finish and comes in 86 inch and 120 inch heights, so confirm the Stanley unit is supplied in a height that matches your frame before swapping.
5) We need a mullion for a fire rated pair of doors. Can we use the Stanley QRM311 instead of the Sargent 12-980?
The Sargent 12-980 is a ULC listed fire rated removable mullion and is suited to both fire rated and non-fire rated openings, which is why it is the direct answer on a fire rated pair. The Stanley QRM311 is a Grade 1 mullion in the QRM300 Series; verify its fire listing against the label on your opening before substituting, since a fire rated pair must be fitted with a mullion carrying the matching listing.
6) Our frame opening is taller than a standard 86 inch mullion. What should we order?
The Sargent 12-980 is offered in an 86 inch standard height and in a 120 inch height for taller frames, so the taller size covers openings above standard door height without moving to another brand. If you are comparing against Stanley, the QRM111 and QRM311 are Grade 1 mullions in the QRM100 and QRM300 Series respectively; confirm the height offered before specifying either on a tall opening.
7) What finish does the Sargent 12-980 come in, and can it be painted to match my frames?
Gray prime coat only, over steel. Prime coat is exactly that, a primed surface meant to be field painted, so if you need the post to match a bronze or painted frame you finish it on site. There is no factory architectural finish option on this mullion.
8) Is the Sargent removable mullion strong enough for a high traffic commercial entry?
It is a commercial product, built from heavy duty steel in a size 2 rectangular profile. Steel is the point on a removable mullion: it takes the latch load from both leaves and gets knocked by carts and dollies in corridors, schools, and warehouses. Aluminum posts do not hold up the same way in that service.
9) What else do I need besides the mullion to finish a pair of doors?
The mullion is the post only. You still need a rim exit device for each leaf, and on a fire rated pair those devices have to be fire rated too. Installation involves preparing the frame at the head and the floor, drilling and routing per the manufacturer template, and securing the mullion top and bottom, so plan on floor and header attachment points being available at the opening.
10) What other removable mullions could I use instead of the Sargent 12-980?
Stanley Security offers mullion hardware in two families we carry: the QRM111 from the QRM100 Series and the QRM311 from the QRM300 Series, both Grade 1. They are the alternative if you are already standardized on Stanley exit hardware at the facility. The Sargent stays the choice where the opening is fire rated and you want a ULC listed post in steel with a prime coat for field painting.
11) What is the difference between the Stanley QRM111 and QRM311 mullions when cross-referencing a Sargent 12-980?
Both are Grade 1 mullions, but they come from different families: the QRM111 is part of the QRM100 Series and the QRM311 is part of the QRM300 Series. If you are cross-referencing a Sargent 12-980 removable mullion, that series split is the first thing to settle, because the mullion has to match the exit device family and the frame height on the opening. The Sargent 12-980 itself is a steel removable mullion supplied with a gray prime coat finish.
12) Do I need a mullion at all, or is there a simpler option for a double door with exit devices?
A removable mullion such as the Sargent 12-980 is the option when you want each leaf to carry a rim exit device and still be able to pull the center post for wide loads. The Stanley QRM111 and QRM311 are the Grade 1 mullion alternatives if you are cross-referencing brands. If the opening never needs a clear width and you are willing to change the devices, a vertical rod or mortise exit pair removes the center post entirely, but that is a device change, not a mullion swap.
