Sargent 12-HCL980 GRAY 86 – Frequently Asked Questions

1) What is a removable mullion like the Sargent 12-HC-L980 used for on a pair of doors?
A removable mullion stands in the center of a double-door opening so each leaf can carry a rim exit device instead of vertical rods. The Sargent 12-HC-L980 is a lockable steel mullion that drops into the opening, gets locked in place, and can be removed with a key when you need the full clear width for moving equipment or furniture through. It is fire rated and ULC listed, so it can be used on fire-rated pairs, and it is built to hurricane code for coastal work.
2) What heights does the Sargent 12-HC-L980 mullion come in?
Two lengths are offered: an 86 inch standard height and a 96 inch option for taller openings. Both come in the gray prime coat finish. Measure your frame opening height before picking, since the mullion has to span from floor to header.
3) Can I use the Sargent lockable mullion on a fire-rated pair of doors?
Yes. The 12-HC-L980 is a fire rated mullion and carries a ULC listing, which is what a fire-rated double-door opening with rim exit devices requires at the center. Match the mullion height to the opening and keep the rim devices and strikes fire labeled as well.
4) What is a comparable removable mullion to the Sargent 12-HC-L980 if fire rating and hurricane code compliance are not required?
The Stanley Security QRM111 is a Grade 1 mullion in the QRM100 Series, and the Stanley Security QRM311 is a Grade 1 mullion in the QRM300 Series. Both serve the same role of dividing a pair of doors so exit devices can latch, but the Sargent 12-HC-L980 is the one specified as a lockable steel mullion that is both fire rated and hurricane code certified, with a ULC listing. If the opening is a non-rated pair in an inland building, a Grade 1 Stanley mullion covers the function; if the pair is a fire-rated assembly or sits in a coastal wind-borne debris zone, the 12-HC-L980 is the one to hold.
5) Mullion or surface vertical rod devices for a pair of doors?
A mullion plus two rim devices keeps all the hardware on the door faces at push-bar height, which means less to damage and less to adjust than rods running to the header and threshold. The tradeoff is the mullion sits in the middle of the opening and has to be unlocked and lifted out when you need full clear width. Vertical rod devices leave the opening clear at all times but add top and bottom latching hardware to maintain. For high-traffic commercial pairs where equipment moves through occasionally, the removable mullion is the usual call.
6) Does the Stanley QRM311 mullion lock like the Sargent 12-HC-L980 does?
The Sargent 12-HC-L980 is a lockable mullion with an integrated locking mechanism, supplied less cylinder so a cylinder can be added to match the building keyway. The Stanley Security QRM311 is catalogued as a Grade 1 standard mullion in the QRM300 Series. Where a guard or maintenance crew needs to key-remove or secure the mullion itself, the Sargent lockable version is the one built for that.
7) What is the difference between the Stanley QRM111 and QRM311 when cross-shopping against a Sargent steel mullion?
The Stanley Security QRM111 belongs to the QRM100 Series and the QRM311 belongs to the QRM300 Series; both are Grade 1 mullions. The Sargent 12-HC-L980 is a separate approach again: a rectangular steel mullion in gray prime coat, 86 inch standard height with a 96 inch option, carrying fire rating and hurricane code compliance. Match the series to the exit devices already on the pair of doors, since mullion and device families are engineered together.
8) For a coastal school or healthcare pair of doors, which mullion should be specified?
The Sargent 12-HC-L980 is the one built for that case: steel construction with both fire rating and hurricane code compliance, ULC listed, in gray prime coat that accepts a field topcoat, and called out for educational facilities in coastal areas, healthcare institutions and government buildings. The Stanley Security QRM111 and QRM311 are Grade 1 mullions in the QRM100 and QRM300 Series and are the general commercial alternative where wind-borne debris requirements do not apply.
9) What finish is the Sargent 12-HC-L980 mullion and can it be painted?
Gray prime coat, both lengths. The primer is there for corrosion protection and to take a field-applied topcoat, so you can paint it to match frames or a tenant color spec on site. There is no plated architectural finish option on it.
10) Is the Sargent 12-HC-L980 mullion suitable for a school or hospital entrance?
It is a commercial-duty part, steel construction, aimed at fire-rated openings in buildings like schools, healthcare facilities, government buildings and multi-tenant residential, with the hurricane rating added for coastal sites. For an institutional buyer standardizing openings, the two heights and the single prime-coat finish keep the spec simple across a facility.
