### ⭐⭐⭐⭐⭐ Make Sure It Fits. It Got My Job Done
*by D***D on July 6, 2024*

The hook style latch and the sliding patio door keeper both work exactly as expected. Once I ensured they fit correctly, the installation was straightforward and hassle-free. The product's sturdy extruded aluminum build with a white finish blends seamlessly with my door, providing a secure hold. Similarlywith its diecast aluminum finish, offers a robust and durable solution for my sliding patio door.The key to success with these products is making sure they’re the right fit for your specific door. As long as you confirm the dimensions, I believe you probably find them to be reliable and long-lasting products that fits your needs.

### ⭐⭐⭐⭐⭐ Easy to mount but requires few spacers
*by F***2 on December 11, 2019*

The product is great and was relatively easy to install. The only problem is it requires few washers to set it properly for the door hook (or whatever the mechanism is that latches on the keeper) to latch on. First I installed it without the washers and the hook wouldn't latch on and then I added three washers each (please don't ask me about the thickness of the washers, whatever I found in my pile) and screwed it on and the door hook latched on and works nicely. The manufacturer should include few washers or other spacers to help with this as I am sure I am not the only one to face this issue. Hence my reason for the 3 stars. Otherwise it'd have been a five star.

### ⭐⭐⭐⭐⭐ Works great
