Keyed Patio Sliding Door Lock, with Steel Bolt, Aluminum Finish

Sturdy deadbolt considering its size and price point. When placing unit on upper door edge corner of interior side of wood-framed sliding glass patio door, it's difficult to find a portable power drill with a chuck diameter small enough to provide sufficient clearance to align the 1/2"hole in the door frame header with the steel rod. Also, the two mounting screws used to secure the lock's body to the door edge might be too short to prevent it being pried off during an intrusion-I substituted 2 1/2" #10 stainless wood screws. I mounted these units on three doors and am pleased with the result. In locked position, it might be difficult for children to unlock unit in an emergency. This item is an asset in a "layered" defense against intrusion when accompanied by a security bar, sturdy lockset and a 9mm.

Not much for directions besides drill bit size, but once i played around with it for a bit, i figures how to mount it up. So much better than using a closet rack stick you have to pick up and set down everyday. Everyone should have one of these of their sliding door.

The patio door lock is okay, but not suitable for my needs and I will return it. I was looking for a patio door lock that I could lock and unlock from the outside. On my patio door, it is designed to be installed on the inside of my home. That does not work for me and is not what I hoped it would do. I guess that is partially my fault. It looks like a good product , but not good for my application.

Seems to be quality, although I had to modify the mounting that went to the door frame. It wasn't nearly long enough to go past the trim work. The triangular shaped piece needs to be about 3/4 to 1" longer to be able to secure it to the door frame not just the trim.Works good overall.

I saw one of these in a hotel that I stayed on their patio door and thought it would be a good idea for my home. It's durable and wasn't hard to install. I feel more secure with it.

product was as advertised, instructions were very vague and took a little studying to install, watch out for the little wire clips as they can fall out during unpacking and installation, they can be hard to find-I know! But product works perfectly and is what I needed.

As described.Took a few minutes to install. Screws are bad quality but the item itself is good

I had one that was actually on my front door, and when I went to look at local hardware stores found they no longer sold.. happy that I found on Amazon!Easy install, comes with multiple hardware ( different size screws ) . Clean set up.
