  • 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
