Slider door security

Question

I saw in one of your discussion threads about a user wanting to add security to a sliding patio door where the moving door is in the outside track. You suggested that product code 80-027 might help.

My son just bought a house with such a door (not sure what brand) and I want to know how can you know whether it's safe to drill holes for this product without cracking the glass? Any suggestions or tips?

I'm a bigger fan of the 80-006 bar, which has a metal bracket when using it on an exterior sliding glass door. I believe either lock would work, it depends which one you like better. Also, you must definitely be careful not to damage the glass in the door when installing either. The rule of thumb is not to pass the past the mounting screw holes on the glass side of the handle. The glass itself goes into the door frame approximately 5/8" around the perimeter of the day light opening.
