Schlage

We have X-10-DOR™ designs for the present non-locking Schlage F and FA Series residential lever handles plus their Dexter line and discontinued solid brass E Series. There are limitations of the X-10-DOR™ designs on vintage and function. You will need a deadbolt on your door when you extend the handle to secure it.
Use the pictures below to help identify the lever design you have. Look for a pin hole at 3 or 9 O'clock in the lever's neck to confirm you have the present version of the F/FA handle (click for example).

NOTE: we do not have a solution for the previous F/FA versions (crimp pierce or rectangular release tab in lever's neck) or any of their knobs.
