DOORKNOB LOCK-OUT DEVICE – The Defender Security doorknob lock-out device can be placed directly over the doorknob to prevent access to the keyhole.
COVERS KEYHOLE – This doorknob security device is not designed to prevent turning an unlocked knob, but rather to block access to the locked keyhole, effectively keeping other keyholders out.
REMOVABLE – The durable diecast cylinder is held in place with an O-ring and is removable 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 round doorknobs that have a max diameter of 2-7/8”. Note that the shaft cut-out is oval/oblong in shape and measures 1-3/4 in. x 1-1/2 in., so it may fit loosely over some doorknobs with round, 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 can be used in any situation where you want to prevent others with keys from unlocking the doorknob.
