# FHC Door Knob Lock-Out Device - Keyed Alike - Gray Diecast (Single Pack)

The FHC Door Knob Lock-Out Device - Keyed Alike - Gray Diecast (Single Pack) is part of FHC's screen-patio-doors hardware line.

## Description

Overview 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. 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 inch outside diameter. Will not work on knobs that are larger than 2-7/16 inch in diameter. Note that the shaft cut-out is oval/oblong in shape and measures 1-3/4 inch x 1-1/2 inch, 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 Prime-Line part S 4181 for lever-type door knobs.
