Sargent L980 GRAY 86 – Frequently Asked Questions

1) What is a removable mullion like the Sargent L980 for, and do I need one on my pair of doors?
A removable mullion is a vertical post that stands between a pair of doors, giving each leaf something to latch into. The L980 is the lockable T-shape version in extruded aluminum. You need one when you want to run rim exit devices on both leaves of a double door: each device latches into the mullion instead of into the other door. When the opening has to pass something wide, the mullion unlocks and lifts out. If your pair is already set up with surface or concealed vertical rod devices latching at the head and threshold, you do not need a mullion at all.
2) How tall an opening will the Sargent L980 mullion cover?
Two heights are sold: 86 inches, which is the standard for a typical commercial frame, and 120 inches for tall openings. Both come in the gray prime coat. Measure your frame height before picking, the 120 inch is cut for openings the 86 inch will not reach.
3) Does the Sargent L980 mullion come with a cylinder?
No. The locking mechanism is built in, but the cylinder is a separate order. Plan to add a mortise cylinder keyed to your building's system so the mullion keys alike with the rest of the openings.
4) Is the Sargent L980 mullion Grade 1 and fire listed?
Grade 1 under ANSI/BHMA, and ULC listed. For a facility standardizing on Grade 1 exit hardware, the mullion carries the same grade as the devices latching into it. Grade 1 is the heavy-duty commercial tier, which is what high-traffic openings in schools, hospitals and offices are typically specified to.
5) What is a cross-brand equivalent to the Sargent L980 mullion for a pair of doors with Grade 1 exit devices?
The Sargent L980 is a removable T-shape mullion in a 2 1/2 inch extruded aluminum profile, rated to ANSI/BHMA Grade 1 and ULC listed, supplied in a gray prime coat for on-site painting. The closest cross-brand counterpart is the Stanley Security QRM111, a Grade 1 mullion from the QRM100 series. Both are Grade 1 mullion hardware for double door openings, so either suits a Grade 1 exit device pair; the L980 carries the integrated locking mechanism and the gray primer finish, and it is offered in 86 inch and 120 inch heights.
6) What finish does the Sargent L980 mullion ship in, and can it be painted to match our frames?
It ships in gray primer only, and that is deliberate: the prime coat is meant to be field painted, so you can match the mullion to the door frames or the architect's color on site. Budget for the paint and the labor, since it does not arrive in a finished architectural color.
7) What does the 2 1/2 inch T-shape profile on the Sargent L980 mean for my opening?
The mullion post is a 2 1/2 inch extruded aluminum section in a T profile. That is the width standing in the middle of your pair, so subtract it from the clear opening when you are checking whether a cart, a gurney or a piece of equipment will pass. Pulling the mullion out gives the full opening back.
8) What prep does installing the Sargent L980 mullion need in the frame and floor?
It anchors top and bottom, so the frame head and the floor both get drilled per the Sargent template. Route and drill before you hang the devices, then torque the mounting hardware to spec and cycle the lock through its full travel to confirm alignment. On a concrete slab or a finished floor, know what is under the bottom anchor point before you drill.
9) What other Grade 1 removable mullions are there besides the Sargent L980?
Stanley Security sells Grade 1 mullion hardware in two lines: the QRM111 from the QRM100 Series and the QRM311 from the QRM300 Series. Both are Grade 1 like the L980. Where the Sargent differs on the record is the detail it publishes: a 2 1/2 inch extruded aluminum T-shape, a lockable post with the cylinder ordered separately, gray primer for field painting, and a choice of 86 or 120 inch height. If your specification calls out a particular height or a paintable primer, the L980 states both.
10) Can I lock the Sargent L980 mullion in place so staff cannot remove it?
Yes, that is the point of the lockable version. The post locks into position and only comes out for someone with the key, so a shipping or receiving crew cannot pull the mullion and leave the pair latching to nothing. Order the cylinder with it, since the lock is supplied without one.
11) What is the difference between the Stanley QRM111 and QRM311 mullions when cross-referencing a Sargent L980?
The Stanley Security QRM111 and QRM311 are both Grade 1 mullions, but they come from different families: the QRM111 is QRM100 series and the QRM311 is QRM300 series, so parts and prep between the two are not interchangeable and the series has to be matched when specifying. Against either, the Sargent L980 is the T-shape 2 1/2 inch extruded aluminum removable mullion with an integrated locking mechanism, ULC listed and finished in gray primer for site painting. If a locksmith is keying the mullion into the building's system, the L980 takes a cylinder, ordered separately.
12) Can a Stanley QRM mullion be used in place of a Sargent L980 on a tall opening that needs a painted finish?
The Sargent L980 is the one specified with the height range and the paintable finish already defined: a standard 86 inch height with configurations up to a 120 inch maximum, and a gray prime coat intended to be painted on site to an architectural color. The Stanley Security QRM111 and QRM311 are Grade 1 mullions in the QRM100 and QRM300 series respectively, and height and finish for those have to be confirmed against the series before substituting. For a tall frame that will be field painted to match the storefront, the L980 in the 120 inch size covers both requirements from a single part.
