Pictured here is a typical Schlage F Series Plymouth design entrance knob set.
Schlage have been selling versions of this Grade 3 product across the market for about 15 years now.
The most common complaint, from an overwhelming quantity of purchasers of this product, is the ease of ability to get locked out.
You see, the typical F Series knobset was designed by someone without taking into consideration the pitfalls of the classic emergency escape mentality.
Until a recent product update that has dramatically changed this product (and all F series knobs too), Schlage, in their infinite wisdom, had allowed the inside turn button to actually lock the outside of the knob, while still allowing the inside of the knob to remain unlocked.
That poorly designed feature, was to maintain emergency egress (escape) function to comply with the International Building Codes demands. But so many people found themselves accidentally locked out of their homes as a consequence. It is not uncommon, to lock the door, using the little turn button inside and then "forget" that the lock is locked, when turning the handle to exit, effectively locking yourself out. (I have seen multiple instances of different people accidentally locked out in their underwear, from this).
Schlage have answered the demands of the market and converted the new F series line, so that turning the inside knob, actually unlocks the outside handle.
I expect that the thousands of locksmiths across the world who have made so much money over the years from attending to lockouts, are bitterly disappointed in this turn of events, but good on Schlage for stepping up and answering the call of the thousands of bitter customers who have used these products for so many years.
Really marvelous locksmith services you are providing.
