Spring-loaded and strong. The 28 Series custodial lock provides tamper-resistant lock up. A slot in the housing requires a special key to operate the lock. Rotating the key 90 degrees locks or unlocks the sash. One end of the key is removable in both the locked and unlocked positions; the other end—only in the locked position allows the key to act as a handle when operating the vent.
