Prime-Line S 4180 Door Knob Lock-Out Device - Keyed Alike, Diecast, Gray (Single Pack)

The Defender Security doorknob lock-out device is designed to be mounted directly over the entry doorknob to prevent access to the keyhole, effectively blocking unauthorized access by key. Constructed from durable diecast, this lock-out device can be used in a variety of applications, including evictions, rentals, home sales, job sites, in-home and in-office storage rooms, to keep other keyholders out even if they possess a key to the door.

The cylinder of the lock-out device is held in place with a removable O-ring, allowing for easy cleaning when the device is unlocked and open. Importantly, the cylinder cannot be removed when the device is closed and locked, enhancing the overall security.

This lock-out solution offers a quicker and easier alternative to replacing the entire knob and lock system on a door, while still providing the necessary level of protection. The maximum outside diameter of a round knob that can be secured with this device is 2-7/16 inch.

Note that the shaft cut-out of the lock-out device is circular in shape, measuring 1-3/16 inch, which may result in a loose fit over doorknobs with smaller diameter slender shafts. It is important to measure your door's handle diameter to ensure a proper fit inside the lock-out device.

Designed to lock around the door knob and prevent the knob from turning, this lockout device is often utilized in apartment evictions. The Defender Security doorknob lock-out device effectively covers the keyhole on the locked entry doorknob, preventing access by other keyholders, without impacting the ability to turn the door handle.

For users' convenience, the durable diecast cylinder is held in place with an O-ring that is removable for cleaning when the device is unlocked and open. However, the cylinder cannot be removed when the device is closed and locked, ensuring the continued security.

It is important to note that users should check for any keys that may have shifted around during transportation and are now inside the lock-out device.

In summary, the Defender Security doorknob lock-out device offers a versatile and effective solution for securing entry doors in a variety of settings, from evictions and rentals to job sites and home offices. Its durable construction, removable cylinder, and ability to fit a range of doorknob sizes make it a practical choice for those seeking to prevent unauthorized access while avoiding the need for a complete door lock replacement.
