I have been looking for a way to make my "builder's special" vinyl slider more secure. A length of 2" PVC pipe helps keep it from sliding, but I wanted lift protection too. This has filled the bill. It went onto my cheap POS slider in about 15 minutes. It would've been about 10 minutes had I positioned it correctly the first time. Two small holes into the door and one large hole into the frame. Works like a champ! Not 100% fool proof, but does give me a little peace of mind.

This is the best answer without full length bolt in wooden door. This application used with vinyl clad door and window. Great solution.

Used to use a pice of wood as extra security on my patio door. This is much easier and just as secure.

I used a 15/16" bit for the main bolt hole as I didn't have a 12mm bit. I ran the drill bit in and out of the bolt hole and was able to get the bolt tension nice and snug when locked. Installed it on a vinyl glass sliding door. Used the longer lock body screws that were for a wood frame instal, they have an assortment of screws for different doors, the longer screws grabbed the vinyl better I felt giving a real stout attachment feel. Use pilot holes on ever screw point and it should be a great backup lock system.

This lock was bigger than I expected but in a good way. Seems very solid and does the job expected. I would buy it again
