Sliding Window Lock
This Sliding door keyed lock adds additional security to your sliding door or window, it can lock the door or limit the opening distance to prevent your kids from falling off from the building or burglars pry or lift your door to get in your house.
2 Ways to Install
The first way you can choose is to install the metal plate to hold the lock bolt as in the picture below, it’s easy and compatible, but you also need to know the distance from sash edge to glass should be more than 6mm, or else you can’t close the window.
The second way you can use is to drill 2 holes to hold the lock bolt, one is for window close, the other one is for ventilation, and you need to know the drilled hole needs to be more than 20mm away from the edge of the sash, to avoid the window glass breaking when you’re drilling.
