Key Operated Custodial Lock

Spring-loaded and strong, Truth custodial locks provide tamper-resistant lock-up. Rotating the key 90 degrees locks or unlocks the sash. A slot in the housing requires a special key to operate the lock. One end of the key is removable in both the locked and unlocked positions; the other end--only in the locked position allowing the key to act as a handle when operating the vent. 28 Series custodial locks can withstand up to 300 lb. of forced entry per locking point.
