My father has Alzheimer's and left the house so we wanted to secure the back sliding door. Luckily he was found quickly. This product did a great job of securing the door. He can't escape without supervision now. Thank you and I recommend it.

The quality is very good, unlike 3 other types of keyed window locks that I had in my house. Usually these types of window locks aren't well made - they get stuck, hard to get key out, hard to push latch in, thin metal. Not this Prime-Line lock. It's solidly built and all operations are smooth. It comes with two ways of mounting as shown in the picture. Each way had 2 pieces, so that the window can locked fully or at a partially open position, which is good for hot summer days. Installation tip: drill pilot holes before driving the screws in to avoid cracking the wood. Think about where glass is usually inserted into the wood to avoid drilling into glass and breaking it. There's sharp dimple at the tip of the bolt for marking the hole on the other side. Use the mark to position drill bit.
