Secure entry doors quickly and effectively with this door knob lock-out device designed to block access to the keyhole on standard round door knobs. Ideal for rental properties, home sales, evictions, vacant homes, construction sites, storage rooms, and commercial facilities, this lock-out device helps prevent unauthorized entry by individuals who may still possess a key. It provides a faster and more economical alternative to replacing the entire lockset while maintaining control over property access.
Constructed from durable diecast metal with a gray finish, this lock-out device is designed to fit directly over the exterior door knob and conceal the keyhole from access. When closed and locked, the device prevents keys from being inserted into the lock cylinder, helping property owners, managers, contractors, and business operators maintain security. Unlike traditional lock changes, this solution allows temporary access control without permanent modifications to the existing door hardware.
The lock-out device is secured with a removable O-ring that allows the cylinder to be removed for cleaning when the unit is unlocked and open. For added security, the cylinder cannot be removed while the device is locked in place. Designed for round door knobs with a maximum outside diameter of two and seven sixteenths inches, this unit is keyed alike for convenient management of multiple devices. Whether securing a rental property, restricting access to a storage area, or controlling entry during a renovation project, this lock-out device offers dependable protection, durability, and peace of mind.
