Door Guardian Stick-On Safety Lock
The Guardian Stick-On Safety Lock is a unique, all-purpose safety lock. Similar to The Window Guardian, The Guardian Stick-On Lock uses high quality 3M adhesive instead of screws—brilliant! This design allows for more versatile applications, including places where screws/hardware cannot be or would rather not be used. Some unique places this lock can be installed are on glass doors and windows, such as outward opening casement windows, and outward opening doors. No screws also makes it much easier to install in metal casework and will not cause damage to glass or other surface where installed.
