Same mortise body, different job on the outside lever

Most of the Yale 8800FL numbers you will see on a school or office hardware schedule describe how the outside lever behaves. The mortise body is the same and the Augusta lever is the same. What changes is whether the lever is locked by key, by a thumbturn, or not locked at all. This article covers the no-deadbolt versions: 8807, 8808, 8809, plus the 8829 and 8833 that people often confuse with them.

Yale is now sold under the Accentra name. The catalog describes it as the commercial line formerly known as Yale, so a lock called out as Yale on a drawing is the same lock. These are heavy-duty mortise locks with a Grade 1 rating for high-traffic openings.

What they share

• Grade: ANSI/BHMA Grade 1, built on the 8800FL mortise chassis.
• Backset: 2-3/4" only.
• Door thickness: 1-3/4" standard.
• Armor front: 8" x 1-1/4".
• Latchbolt: 3/4" throw, stainless steel.
• Trim: Augusta lever, non-handed, single cylinder.

There is no deadbolt in any of these. If the door needs a deadbolt tied to the lever, those are the 8847, 8860, 8861 and 8867 models in the same 8800FL family. The numbers here are for doors where the latchbolt does the work.

8807FL: the entrance lock

The catalog lists the 8807 as the entrance function. The outside lever is locked and unlocked by key. The inside lever is always free to exit. The catalog calls it the workhorse setup for offices and main entrances, which is fair: it is the function most people expect when they say "a lock with a key." The AUR8807FL in satin chrome is the reference listing. Use it where the door should be locked at night, open during the day with the key, and always usable for someone leaving.

8808FL: the classroom lock

The 8808 is the classroom function. In the catalog's words, it locks and unlocks the outside lever by key from the corridor, and the inside lever is always free for egress. The practical point of a classroom function is where the key goes: only the teacher or staff in the corridor can lock the door, and everyone inside can leave. The AUR8808FL in satin chrome is the listing. The same part number is also in bright chrome in our catalog if the other hardware on the hallway is chrome.

On paper the 8807 and 8808 look similar, because both are keyed from outside and free from inside. The difference is the name on the hardware schedule. Order the number the schedule gives. If the schedule is missing, the door's use tells you: a teaching space gets the classroom function, an administrative entrance gets the entrance function.

8809FL: classroom or office, with a thumbturn

The 8809 is listed as classroom with thumbturn, in the catalog as the classroom or office function. The catalog description is the same as the classroom lock: the outside lever is locked and unlocked by key from the corridor, and the inside lever is always free. The difference is in the title: with thumbturn. Our catalog does not break out the thumbturn behavior beyond the name, so we do not guess at it here. If the thumbturn matters for how the door has to work, send us the hardware schedule and we will confirm against the listing before you order. The AUR8809FL in satin chrome is the one to look at.

8829FL and 8833FL: not entrance locks

A buyer scanning the list sometimes picks one of these thinking it is a variant of the entrance lock. It is not.

• The 8829 is the closet function. The catalog says the outside lever is always locked and key-access-only, and the inside lever always allows free egress. The AUR8829FL suits a janitor closet or a storeroom where nobody comes in without a key.
• The 8833 is the exit function. It provides latching with free, unimpeded egress from the secured side. The AUR8833FL is the one for a door that people leave through but that does not have a normal way in from the other side.

If the door needs to be entered with a key, these two are the wrong lock.

A quick way to choose

• Office or main entrance, key outside, free exit: 8807.
• Classroom, key from the corridor, free exit: 8808.
• Classroom or office function with a thumbturn on the schedule: 8809.
• Closet or storeroom, outside always locked: 8829.
• Exit-only latch: 8833.

The storeroom function, with and without the indicator, has its own write-up: the Yale 8800 storeroom lock.

Before you order

1. Confirm the backset is 2-3/4". The 8800FL does not come in another.
2. Confirm the door is 1-3/4" thick. That is the standard for these locks.
3. Confirm the finish. The listings linked above are satin chrome, and the 8808 is also listed in bright chrome. Tell us the finish on the rest of the door hardware.
4. Check the mortise pocket on the door. If you are replacing an older mortise lock, measure the pocket and the faceplate. If you are not sure, send us a photo of the edge.

Common questions

What is the difference between the 8807 and the 8808?

The 8807 is the entrance function and the 8808 is the classroom function. Both are keyed from outside with a free inside lever. Order the one that matches the hardware schedule.

Do these locks include a deadbolt?

No. These models are the latchbolt-only versions. The deadbolt models are the 8847, 8860, 8861 and 8867.

Is the Yale 8800FL a Grade 1 lock?

Yes. The catalog lists it as ANSI/BHMA Grade 1 for high-traffic commercial and institutional doors.

Is Accentra the same as Yale?

Yes. The catalog describes Accentra as the commercial line formerly known as Yale.

Can I use the 8829 as an entrance lock?

No. The 8829 is a closet function where the outside lever is always locked and operated by key only.
