Quick Tip

All exit devices can take outside trim, which bolts onto the device from the outside.

Device Finishes

Finishes are pretty easy to understand.  The only confusing issue is all finishes have two names.

US3, for example is the "US Name" and 605 is it's BHMA equivalent.  They mean exactly the same thing.

Either name can be used when ordering.

Device Functions

The most confusing aspect of exit devices is outside trim, which provides the device function.

The functions below show the 22 series, but the same idea holds true for all series.

Exit Device Functions
Trim	Designation	Notes
None	EO Example Model: 22EO	EO = Exit Only No outside trim
	L Example Model: 22-L	L = Lever Key freezes lever in place.  Use key again to free the lever.
	DT Example Model: 22-DT	DT = Dummy Trim Trim acts as pull handle only.
	NL Example Model: 22-NL	NL = Night Latch Always locked from the outside.  Use key to retract latch.
	NL-OP Example Model: 22-NL-OP	NL-OP = Night Latch, Optional Pull Same as NL, but customer furnishes their own pull handle.

If you think of outside trims as ''bolt-on'' accessories you'll be ahead of the game.

Most people have trouble getting the big picture.  Remember, the exit device always lets you out from the inside so there is no function to think about from that side of the door.

If you want to allow people in from the outside of the door, you'll need to "bolt on" some trim.  It's just like bolting on 1/2 of a lock.  And locks come in different functions.
