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, effectively preventing unauthorized access by key. This device is often used in various applications, such as evictions, rentals, home sales, job sites, and in-office storage rooms, where the aim is to keep other keyholders from accessing the keyhole and unlocking the door.

Constructed from diecast and finished in gray, the lock-out device is designed to lock around the door knob, preventing the knob from turning. The durable, diecast cylinder 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.

The maximum outside diameter of a round knob that can be secured with this device is 2-7/16 inch. The shaft cut-out is circular in shape and measures 1-3/16 inch, which may allow for a loose fit on doorknobs with smaller diameter slender shafts.

This lock-out device provides a quicker and easier solution than replacing the entire knob and lock system on a door, while still offering the necessary protection. It is designed to keep the keyhole on the locked entry doorknob from being accessed, not the handle from being turned, effectively keeping other keyholders out.

It is important to note that users should look for the keys inside the lock-out device, as they may have shifted during transportation. By using this device, individuals can prevent unauthorized access to their doors, ensuring greater security and control over their property.

In summary, the Defender Security doorknob lock-out device is a versatile and effective tool for securing entry doorknobs, with a range of applications in various settings. Its durable construction, removable cylinder, and ability to accommodate different knob sizes make it a practical solution for those seeking to restrict access to their doors.
