The Accentra COCN 8808K (formerly Yale 8800 Series) is a heavy-duty Classroom Lock Function mortise lockset built for commercial and institutional openings. It is certified to ANSI/BHMA A156.13 Series 1000, Grade 1 -- the highest operational and security grade the standard defines -- and carries the Copenhagen (COCN) knob on the Camden escutcheon.
Built for openings that are opened and closed thousands of times a year, it uses a wrought steel, zinc dichromate plated case and a 3/4" throw stainless steel anti-friction latchbolt. Supplied in 626, it is field reversible and ships with the door prep and installation drawings for the trim shown.
Function Details: Classroom Lock (ANSI/BHMA F05)
- Typical Application: For classroom, office, or utility room doors — the openings this function is written for.
- Outside Knob Works Until It Is Locked: Latchbolt retracted by knob/lever either side, except when outside knob/lever is locked by key — the outside knob retracts the latchbolt normally, and stops the moment the lock is set against it.
- Life-Safety Free Egress: Inside knob/lever always active — the inside knob is never locked, so a single motion always gets a person out.
- Key Entry While the Outside Stays Locked: Latchbolt can be retracted by key when outside knob/lever is locked — with the outside knob locked, the key withdraws the latchbolt for that one entry and leaves the outside knob locked behind it, so the room does not have to be unlocked to let someone in.
- Free Egress, Outside Unaffected: Operating inside knob/lever retracts latchbolt, but outside knob/lever remains locked — anyone inside leaves by turning the inside knob in a single motion, and doing so does not unlock the outside knob behind them.
- Anti-Shim Protection: Deadlocking latchbolt — a small plunger beside the latchbolt rides the strike when the door closes; with it depressed the latchbolt cannot be shimmed back with a card.
Key Performance Features
- ANSI/BHMA Grade 1 Certified: Independently tested to the highest operational and security grade the standard defines, for long service life in demanding commercial and institutional openings.
- 3-Hour Fire Rating: UL and cUL listed for use on fire-rated door assemblies, so the opening stays code compliant.
- Field Reversible: Furnished right hand and re-handed in the field, so one lock suits either door swing without a return.
- Anti-Friction Latchbolt: A stainless steel one-piece latch that closes quietly and resists the drag that wears a latch out on a high-traffic door.
- Mechanical Warranty: Backed for the long term against defects in the mechanical lock.
