About this item

The Sargent 8243 is the apartment corridor door function in the 8200 Series mortise line. ANSI F20. It combines a latchbolt and a 1" hardened stainless steel deadbolt in a single mortise case designed specifically for residential unit entry doors in apartment, multifamily, dormitory, and hospitality applications - any door where a resident needs full deadbolt security from inside and a key is required from outside.

 

How the F20 Apartment Corridor Function Works

 

The 8243 has four distinct operating states, and understanding each one explains why it's specified for apartment entry rather than standard office entrance functions.

 

Key from outside retracts both the latchbolt and the deadbolt simultaneously. The outside trim remains locked after entry - the key does not toggle the outside lever on or off, it only provides momentary access.

 

Thumbturn from inside projects or retracts the deadbolt. When the deadbolt is projected, the outside trim locks automatically. When the resident retracts the deadbolt with the thumbturn, the outside trim remains locked unless they manually disengage it with the toggle.

 

Toggle button controls the outside trim state. The outside lever is locked by projecting the deadbolt OR by operating the toggle. The toggle is the only way to unlock the outside lever without a key. A resident who wants to receive guests freely uses the toggle to unlock the outside, then re-engages it when they want security back.

 

Inside lever always retracts latchbolt and deadbolt simultaneously for immediate egress. Inside egress is never blocked.

 

8243 vs 8245 vs 8247: Picking the Right Function

 

These three are the most common multifamily and residential-commercial functions in the 8200 Series. They're frequently confused on hardware schedules.

 

8243 (F20): Apartment corridor door with deadbolt. Toggle-controlled outside, thumbturn deadbolt inside. For unit entry doors where residents need full deadbolt security.

 

8245 (F21 dormitory/exit): Deadbolt projects from inside by thumbturn. Key or inside lever retracts both. Outside lever locks when deadbolt is projected. Different toggle behavior from the 8243. For student housing and dormitory doors.

8247 (F22 entry/corridor): Outside lever normally unlocked, key in outside cylinder locks it. Different security model - used more in corridor and common area doors than unit entry.

 

If your hardware schedule says "8243" and the door is a private unit entry, that's the right call. If you're unsure between 8243 and 8245, the key question is how the thumbturn deadbolt behaves relative to the outside lever - the 8243 uses toggle control for that distinction.
