Dynasty Hardware Door Closer, Commercial Hydraulic Closer, Self-Closing, Spring Size 4, ADA Compliant, Surface Mount, Sprayed Aluminum, Series 4000

This 4000 model is rock solid and built like it is supposed to last. Had a tricky install on my particular metal shop door so called Dynasty directly. To my surprise, Jason picked up the phone at 6:30pm CST and spent 20 minutes trouble shooting my situation. He helped me find a creative solution and everything turned out great. No more bugs or wildlife entering the workshop! Great customer service. Thank you

The Dynasty Door Closer is exactly as described and works great! It’s a sturdy, commercial-grade product with smooth hydraulic action that closes the door automatically and reliably every time. The installation was straightforward, and the aluminum finish looks sleek and professional. Overall, it's an excellent, high-quality door closer that gets the job done without any issues. Highly recommend for anyone needing a reliable, heavy-duty door closer for commercial or residential use!

I had one of these in the lighter strength, and I liked it so I got this second one. I had noticed with the first one that the screw heads stripped out pretty easily. This one though, the one bolt that ruins the whole thing if it fails, the head ripped off while tightening it. So of course to fix the problem I would have to drill out and replace the bolt which just seemed impossible to me. I left it as is, the arm does not seem it will come off without it on. Alternatively I think I could reposition and move the arm to the bottom. Anyway, complaint about the ripped off bolt head aside, the closer is great. The first one has lasted for years closing my door. This one has a little more pulling power for the heavier door and it works great too. They are very adjustable and easy to install. I like how well it works. I have noticed if you are using it 10 times in a row it gets a little fatigued on the closing part, but comes right back within a minute or so.

Perfect replacement for an old version. Easy to adjust.

after buying many cheaper units that fail within months the quality in this unit can be seen and felt, should last a long time, also VERY strong backcheck!

Works as expected

Long but good instructions and it is needed.

This item fixed a long time issue we had with our door to the garage not closing fully if the main garage door was open. The only issue has to do with the amount of effort now needed to open the door. I am unaware of any adjustment on the unit which allows for a reduced effort to open the door.
