Sliding Door Lock - Sliding Window Security Lock - Extra Long 3-½ Inches Window Security Guard Pin Lock Set for Sliding Doors & Windows - Rampro

The hardware shipped with these pins is terrible. Installed them in some sets of old aluminum sliding glass doors. Predrilled holes, installed the screws manually, and still wound up snapping 5 of the 12 screws. These are the least expensive of these pins on Amazon, so I guess you get what you pay for. Will wind up spending $ for better hardware at Ace.

Especially like the locking ring around the pin when inserted in the door.

While lacking the elegance of the pressure treated 2x4 previously securing our sliding door, this economical solution is simple to install and while not the most robust material, does a great job of preventing someone shimming the latch or lifting the door out of the track. There may be stronger, more expensive options out there, but keep in mind a glass sliding door isn't going to have a burglar pick the lock, they're going to throw a brick through it.

I bought this to replace an older one that is getting some rust, and it is harder for the rod to go in and out of the hole. I just wish that they would make a stainless steel version of this, so I don't have to replace it every couple of years.

It was easy to install and quick. Great replacement for my old one. It works great!

This was easy to install. Drilled a single hole and it was done. Now I don’t worry about someone sliding the window from outside.

This was a very easy product to install and shipped extremely fast.

Small enough but plenty sturdy does the job. A good buy
