HOW A LOCK PRIVACY FUNCTION WORKS
Privacy lock sets are often used for commercial restrooms or dressing rooms, although they do have uses that range all the way from residential to heavy commercial (Grade 1, Grade 2 & Grade 3). In short, a privacy function lock has a clutch that allows a door to be locked and unlocked only from the inside.
Privacy locks sets are not meant to provide security. The primary function of a privacy lock is to let an individual enter a space and allow them to close the door and lock it behind them so that they are not disturbed from the outside for a short time. On the inside of the door lockset, a push or turn button that allows the individual to easily lock the door. A quick turn of the handle unlocks the door when the individual is ready to leave the room.
On the outside of a door installed with a privacy function there is no key lock mechanism. Instead, the lockset has a small raised surface that contains a hole or slot. This a safety feature that allows the door to be opened with a coin, or tool like a flat head screwdriver if it is shut without an individual inside the door to open it.
Although restrooms and fitting rooms are the most popular applications for a privacy function, they do come in other variations such as those commonly used in hospitals that offer a thumb-turn on both the inside and outside of the door in case hospital staff needs to quickly access a patient. Another variation includes an indicator on the outside of the door that tells whether the room is “Occupied” or “Vacant.”

PJ: Hey, this is PJ with CLK Supplies and this is the privacy lock function. Now the privacy lock function is found on grade one, two, and three hardware meaning it's found between the basic residential all the way to heavy duty commercial. Now just like its name, this lock is meant to provide privacy, not security. And what do I mean by that? It means on the outside of the lock, as you can see here, there's a little turn piece where like a normal lock cylinder would go. Okay. Now depending on who makes it and what grade it is, it may have like a little hole here with like you could stick a paperclip in and push it. In this case it has this little turn piece, which you can use just about anything you could use like a quarter. As you can see here, just like that. Or you could use a screwdriver or you could use even the corner of a credit card if you needed. All right, so it's just meant to provide privacy, not really security.
PJ: All right. Now on the inside, you're going to find on this one, there's going to be a push button. Sometimes there'll be a little twist knob depending on the grade and what the manufacturer used here, but they're all going to work about the same way. On the inside you're going to lock it, which in this case you're just going to push it in here. And on this one, if you pull down, it's going to pop open, or if you pull up, it's going to pop open. And from the outside when the button's pushed, this is a clutch function, which I'll put in the notes below. If you don't know what that is, when you pull this lever down, it's not going to activate the lock, right? But as soon as you open the door from the inside, this button's going to pop out. Now it's going to be unlocked. So it's perfect for a bathroom setting, a fitting room setting, anything where you just want to get some privacy and you're not really looking for security. So this is the privacy function. Thanks for watching. We'll see you next time.
