This knob lock-out device is constructed from diecast and comes in a gray painted finish. It is designed to mount over a locked door knob with the purpose of blocking access to the keyhole only. This lockout device is often used in evictions, rentals, home sales, job sites and in-home, or on in-office storage room knobs to prevent others with keys from unlocking the door knob. The maximum diameter of a round knob that can be secured with this device is 2-7/16 in. outside diameter. This lock-out device will not work on knobs that are larger than 2-7/16 in. in diameter. Note that the shaft cut-out is oval/oblong in shape and measures 1-3/4 in. x 1-1/2 in., and it may fit loosely over some door knobs with round, slender shafts. Note: These lock-out devices are for use over keyed/locked door knobs to block access to the keyhole from others who may have keys to unlock the door. See model number S 4181 for lever-type door knobs.

  • 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
  • NOTE - Look for the keys inside the lock-out device as the may shift around during transportation
