This door closer works great, it came with instructions and multiple templates depending on your mounting application or preference. It had all the hardware you need included (even though I feel the bolts were a little on the soft side). After it was installed it has three different adjustment screws so you can make this door close exactly how you want it to. I put it in my side door to my steel building and had to add a few washers because the steel buildings door was a little thinner then your standard door. Overall I’m happy with the product!
