Dynasty 4000 Series Door Closer, Sprayed Aluminum, Spring 4 | Commercial Hydraulic Door Closer, Self-Closing Surface Mount, Adjustable Spring Size 4

Installed closer on door twixt laundry room and garage. Was pleasantly surprised to learn unit could be easily installed on the push (laundry room) or pull (garage) side of the door. Chose garage (pull) side and watched the detailed installation video. Easy one-person job. Works even better than I’d hoped. Pros: Commercial grade. Quality construction. Straightforward installation. Hardware included for installation on wooden or metal doors. Excellent how-to installation videos. Easy to adjust closure speed and latching force (separately). Quiet! Cons: Commercial grade (in a residential setting). Makes door feel a bit heavy. (We’ll get used to it!) No “hold open” feature.

So my downstairs neighbor (Slammy McGee) kept slamming the heavy foyer door late at night, and it would shake my whole apartment every time he did (literally sounded like a bomb was going off). I tried talking to him a few times about it, but it just wasn't sinking in. I looked up the best way to prevent someone from slamming a door, and an automatic door closer was the top recommendation online. This took about 20 minutes to install, and after I set it up, I tried six ways from Sunday to slam the door, and it literally makes it impossible to slam the door (closes whisper quiet even when trying to slam the door). It has adjustments for the speed at which it closes the first 90% of the door, and another adjustment for the last 10% of the door closing. It can be mounted on either side of a door, and comes with hardware to mount it to either the side or the underside of the door frame. Worked great, no more door slamming! -Door slammer outsmarted ;) Did you find this review helpful?

The Dynasty Hardware commercial hydraulic door closer (Size 4) is a solid, reliable choice. It closes doors smoothly and consistently without slamming, and the adjustable speed makes it easy to dial in the perfect setting. Feels durable and well-built, and installation is straightforward. Great option for commercial or heavy-use doors at a very reasonable price.

Part was as a customer said it was

These work great. I reordered and installed three of them now. They are worth the money.

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!

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

Great product. Exactly same size like my broken door swing. Work great.
