FORTSTRONGCommercial Door Closer Heavy Duty (Silver) - Automatic Door Closer - UL Listed Grade 1 ADA Hydraulic Door Closers Commercial Certified - FS-7600

Installation was a breeze once I realized I could just follow the template for the way I wanted to install it. The instructions felt a bit overwhelming and there wasn't a chart showing what screws went where which was a bit frustrating but easy enough to figure out after getting started. After some adjustments with the the sweep the door closes much better than it did with my old unit and I couldn't be happier.

The installation instructions are easy to read and understand even comes with a template for all three ways to install and for both left and right handed doors. It was very easy to see which way was going to work with my door. My only complaint is they don't explain what screws are what and when they are used. Also upon trying to put the arm on like the instructions says (parallel arm for a right hand door, pinion flat at b) it didn't match up quite right, the arm was pushing into the door, so we improvised and switched it. I personally stood for hours trying to figure out what all the screws were for and why the arm wasn't right. I finally gave up and gave it over to my boyfriend who put it up in 30 minutes! We used it on our backdoor so now I don't have to worry about the kids leaving it wide open in this heat or the dog getting out! It's working great cant tell it's there and shuts the door fully without snapping shut on our heels! So far it has saved me from having to run outside after the dog about 10 times just today!

This door closer was really easy to install. My husband helped me out, but it would have been easy enough for me to install alone. I love that the screws and bolts are heavy duty; which means it will last a very long time. There are a few installion options, so it will really work for anyone’s home. I have a 2 year old and a little dog that likes to try to run out the door when my hands are full. Today I didn’t have to worry about hurrying up to get the groceries in the door and juggling things to pull the door closed behind me. Definitely a life saver!

I also think the instructions could use some work, but I was able to install after watching some YouTube videos from other manufacturers. Other than that it works well and seems like a solid closer.

This door closure unit has multiple adjustments, easy to install and it is quiet during use

Falcons got too expensive so I thought I'd try these. They are exactly alike.

My husband was able to replace our old door closer in about 25 minutes without any difficulty. The template definitely made all the difference in making for an easy-quick installation. It's quiet and looks and works great! We chose this over the other brands because of the no questions asked money back or replacement guarantee so if it didn't work out we could get our money back. Overall, it is a high-quality product at an awesome price and guaranteed.

I used a push-side top jamb installation, with the closer unit on the top jamb and the foot on the door. The instructions and the "top jamb" template were in conflict with each other over how to achieve 120-180 degrees of opening freedom. One said that "dimension A" should be 4" from the door edge, and the other said 6.5".Nonetheless, the hold-open functionality is dictated by a nut that you "simply turn counterclockwise". The nut is super thin but has a large diameter, so only my large wrench would open wide enough--but the large wrench is also somewhat fat, making it difficult to stay in place on the nut. When first installed, the door only opens about 75 degrees. The nut required a huge amount of force to turn, and would only move a partial rotation--this was enough to get the door to open about 110 degrees, which was acceptable but far less than I wanted.The seller support provided an immediate reply via automation, and a seemingly human reply within a few days. The first reply asked for photos (which I provided within a day), and indicated that a specialist would have to look into it. Many days later, the specialist quoted me the instructions about simply turning the nut, but apparently didn't read my question which clearly said that I attempted to do so and that it was difficult to apply the required force. Should I be expecting to apply over 150 ft-lbs of torque to the nut? They never answered my followup, and it's insulting to type a detailed question with photos, and have them paste me a sentence from the instructions.I don't know if they were dismissive of my question out of incompetence (reading English shouldn't be hard for a UK company--I mean they did invent the language, after all), or if they are simply too busy to be bothered.Positive things: quality materials and finish on the product. Operation is quiet and (except for opening angle), is functionally solid.Negative things: for my install method ("top jamb"), the instructions and the template were in direct conflict with each other (one of them was probably copy-pasted from a different installation method's details); corporate support was slow, condescending, and ultimately useless.
