The 8833 is the quiet one in the 8800FL family

Most of the Yale 8800FL mortise locks have a function name that tells you the room: classroom, bathroom, dormitory, storeroom. The 8833 is listed as an Exit lock. That is a function, not a room, and it is the one buyers pass over because it sounds like something that belongs on an exit device. It does not. It is a mortise lock with the Augusta lever, a single cylinder and an ANSI/BHMA Grade 1 rating. Yale is sold under the Accentra name now; the listings call it genuine Accentra hardware, the commercial line formerly known as Yale.

What the listing says the function does

One sentence: exit function provides latching with free, unimpeded egress from the secured side. Two things follow from that and nothing else does.

• The door latches. It is not a dummy trim and it is not a lock that leaves the latch retracted.
• Whoever is on the secured side can always leave. No key, no button, no second motion.

That is all the catalog tells us. It does not describe what the outside lever does when the door is pulled shut, whether the key retracts the latch from the outside, or whether the outside lever is fixed. The other 8800FL pages spell their functions out in detail, and this one does not, so we are not going to put words in the manufacturer's mouth. Those answers are on the manufacturer's function chart, and if the door is a retrofit, they are on the lock that is coming off.

Where an exit function earns its place

Think about the doors where the one rule is "never trap anybody": a stairwell door that must always let people out, a door between a corridor and a back-of-house area, or an opening where the other side is meant to stay under control. If the hardware schedule on your job says "exit" for a mortise lock, this is the model family to check first.

If you need the room to be locked against the corridor with a key, that is a different function. See the storeroom models in the 8800FL family. If you need a classroom or an office with the lever locking and unlocking by key, see the entrance and classroom comparison. If the schedule calls for a deadbolt, the deadbolt function piece has the options. The 8833 has none of those jobs.

Eight finishes, one lever

The catalog carries the 8833 in the Augusta lever and these finishes:

Code	Finish	Example
605	Bright Brass	AUR8833FL-605
606	Satin Brass	AUR8833FL-606
612	Satin Bronze	AUR8833FL-612
618	Bright Nickel	AUR8833FL-618
619	Satin Nickel	AUR8833FL-619
625	Bright Chrome	AUR8833FL-625
629	Bright Stainless Steel	AUR8833FL-629
630	Satin Stainless Steel	AUR8833FL-630

A satin chrome 626 also exists in the catalog. Match the finish to the hinges and the closer on the same door. The finish on a lever is the first thing anybody sees, and mixed finishes on a single opening look like a mistake even when they are not.

The AUR is not decoration

AUR is the Augusta lever. The catalog carries other lever styles on the same lock bodies, with different prefixes, and they are not interchangeable on an order. If your hardware schedule gives only the lock number and no lever, ask which one before you buy. The lever prefix guide lists them.

What to confirm before you order

The 8833 listing does not give a backset, door thickness, latchbolt throw or armor front size. The sibling models have those figures, and we do not copy them across. For this one, take them off the opening. A mortise lock fits a pocket cut into the edge of the door, and the pocket is either right or it is not.

1. Check the schedule for the word Exit and the model number 8833.
2. Confirm the function on the manufacturer's chart if the opening is a retrofit.
3. Measure the backset and the door thickness on the existing door.
4. Pick the finish from the eight listed.
5. Decide who supplies the cylinder, since the listing calls it a single cylinder lock.

The whole family is on the Yale page.

What not to assume

Do not assume the 8833 is the same as a passage or privacy function because the egress language sounds simple. Do not assume a key operates the latch from the outside. The listing does not say. And do not order it for a room that needs to lock people out by lever, because that is a different function, and the listing for this model does not describe one.

When the catalog is thin on a model, the right move is to say so and let you decide. A call to us costs nothing. A mortise lock ordered on a guess and sent back costs a week.

If you call us, have these ready

Give us the model number off the lock being replaced or off the hardware schedule, the door thickness, the backset, the finish and the lever style. With those we can confirm the 8833 is the lock you mean before it ships. A mortise lock is not a part you want to return, and the thin spots in this listing are exactly why we would rather answer the question first.
