Institutional Lock Function on Grade 1 and Grade 2 Knobs and Levers

Going over the Institutional Lock Function. This function is found on commercial locks, both knob and lever, Grade 1 and Grade 2. This lock does have a clutch function. Check the link if you don't know what the clutch function is. But essentially, what happens is even when the door is locked, the handle is still going to go up or down, but it's not going to retract this latch here.

 Institutional Lock Function

Both sides of the door have a key cylinder, so the only way to get in or through a door with an institutional lock is with a key.

 Grade 2 lever with institutional lock function

Look at the institutional function as a storeroom lever on both sides. You stick the key in, and you turn it, and while you're turning the key, you're going to see the latch go in. So, the key is going to operate the lock. You don't need to move the lever—the same thing on the other side.


It would be best if you had a key from both sides to open the lock, and you didn't even move the lever up or down. It's all done in the function of the key. So, that's the institutional lock. Thanks, and we'll see you next time.
