This Defender Security doorknob lock-out device is designed to be mounted directly over the entry doorknob to prevent access to the keyhole only, effectively preventing unauthorized access by key. The durable, diecast cylinder is held in place with a removable O-ring for cleaning the cylinder when the lock-out device is unlocked and open. The cylinder cannot be removed when the device is closed and locked. This lock-out device is often used in evictions, rentals, home sales, on job sites, in-home, on in-office storage room knobs to keep other keyholders out, even if they have a key to the door. It is a quicker and easier solution than replacing the entire knob and lock system on a door while still getting the protection you need. The maximum outside diameter of a round knob that can be secured with this device is 2-7/16 inch.

  • DOORKNOB LOCK-OUT DEVICE – The Defender Security doorknob lock-out device can be placed directly over the entry doorknob to block access to the keyhole. Note: Measure your door's handle diameter to ensure it will fit inside the lock-out device.
  • COVERS KEYHOLE – This doorknob security device 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.
  • REMOVABLE – The durable diecast cylinder is held in place with an O-ring and is removable for cleaning when the device is unlocked and open. The cylinder cannot be removed when the device is closed and locked.
  • DIMENSIONS – This lock-out device can protect rounded doorknobs that have a max diameter of 2-7/16 inch. Note that the shaft cut-out is circular in shape and measures 1-3/16 inch, so it may fit loosely over doorknobs with smaller diameter slender shafts.
  • APPLICATIONS – This lock-out device is often used in evictions, rentals, home sales, on job sites, in-home, in-office storage knobs and more. It is used in situations where you want to prevent other keyholders from accessing the keyhole to unlock
