Sargent 980S GRAY 86 – Frequently Asked Questions

1) What does a Sargent 980S removable mullion actually do on a pair of doors?
The 980S is a steel post that mounts in the center of a pair of doors, giving each leaf something to latch into. That lets you hang a rim exit device on each door instead of vertical rod devices. When you need the full opening clear to move equipment through, the mullion comes out and goes back in afterward. It is 86 inches tall and ships in a gray prime coat so it can be painted to match the frame.
2) Should I use a removable mullion with rim exit devices, or vertical rod devices on the pair instead?
Two different trade-offs. With the 980S mullion each leaf takes a simpler rim device latching into the mullion, and there is no rod hardware on the door face and no bottom rod to collect dirt at the threshold. The cost is that the mullion sits in the middle of the opening, so anything wider than one leaf means pulling the mullion out. Vertical rod devices leave the opening completely clear all the time, which is why they get specified where carts and gurneys move through constantly. If the opening is mostly foot traffic with occasional large moves, the mullion is the lower-maintenance choice.
3) Can I use the Sargent 980S on a fire rated pair of doors?
The 980S is ULC Listed. On a fire rated pair, the mullion has to stay in place for the assembly to hold its rating, so a removable mullion in a fire opening is normally keyed or retained so it is not casually pulled. Confirm the mullion, the exit devices, and the door and frame labels are all rated together, because the opening is only rated as a complete assembly.
4) What is a direct equivalent to the Sargent 980S removable mullion?
The Stanley Security QRM111 is a Grade 1 mullion in the QRM100 Series, and the Sargent 980S is a removable steel mullion carrying a Grade 1 ANSI/BHMA rating, so both sit at the same commercial grade for a pair of doors sharing one opening. The 980S is supplied 86 inches tall in a gray prime coat, a ready-to-paint surface, while the QRM111 is catalogued as standard mullion hardware. Confirm the frame height of the opening before swapping, since the 980S is built to a fixed 86 inch height.
5) Is the Sargent 980S mullion painted, or do I have to finish it?
It comes in gray prime coat, which is a base coat, not a finish coat. Plan on painting it on site to match the frame color. If you want a factory finish out of the box, a prime coat mullion is the wrong pick.
6) Is the Sargent 980S mullion rated for high traffic commercial use?
Grade 1 ANSI/BHMA, which is the heaviest commercial rating and what gets written on school, hospital, and government specs. The body is rectangular steel. For an MRO or institutional buyer standardizing across a building, Grade 1 is the line most facility specs draw.
7) What else besides the Sargent 980S mullion do I need to finish a pair of doors?
The mullion is the post only. You still order a rim exit device for each leaf, and the frame needs the top fitting and floor prep the mullion anchors into. Nothing about the exit devices, trim, or cylinders is included with the mullion itself, so specify those separately on the order.
8) What other Grade 1 mullions could I use instead of the Sargent 980S?
Stanley Security makes Grade 1 mullion hardware in two families we carry: the QRM111 from the QRM100 Series and the QRM311 from the QRM300 Series. Both carry the same Grade 1 rating as the 980S. Where the Sargent goes in is usually where the rest of the opening is already Sargent exit hardware, since matching the mullion to the device brand keeps the strike and fitting geometry consistent.
9) What is the difference between the Stanley QRM111 and QRM311 mullions?
They are two different Stanley Security series: the QRM111 is in the QRM100 Series and the QRM311 is in the QRM300 Series, both described as Grade 1 mullions in standard configuration. Because the series differs, the exit device trim and stabilizer parts that mount to one are not assumed to carry over to the other - match the series to the exit devices already hung on the opening. The Sargent 980S is a separate removable steel mullion with its own Grade 1 ANSI/BHMA rating and ULC listing.
10) For a facility standardizing on Grade 1 mullions, which options meet that requirement?
Three carry the Grade 1 rating: the Sargent 980S removable steel mullion, the Stanley Security QRM111 in the QRM100 Series, and the Stanley Security QRM311 in the QRM300 Series. Where the specification also calls for a ULC listing on the mullion, the Sargent 980S carries that listing. For a facility writing one part number across many double door openings, the 980S also arrives in a gray prime coat, which lets the mullion be field painted to whatever color the frames are finished in rather than committing to a fixed decorative finish.
11) If an opening needs full-width clearance for moving equipment, is a fixed mullion an alternative to the Sargent 980S?
No. The Sargent 980S is a removable mullion, which is the point of it - the steel post lifts out so the full width of the double door opening is clear for carts, beds, or equipment, then reinstalls to restore the strike for the exit devices. A fixed mullion is permanently anchored and will not give up that clearance, so it is not a substitute where full-width access is a requirement. The Stanley Security QRM111 and QRM311 are the Grade 1 mullion alternatives to evaluate against it.
12) Is the Sargent 980S suitable for a residential or light duty opening?
No, it is a commercial part. The 980S is built and rated for commercial door hardware use, and a removable steel mullion only makes sense on a pair of doors carrying rim exit devices. A residential double door with standard locksets has no use for one.
