Safety Spring Door Closers, Adjustable Closing Door Hinge, Automatic Stopper Fire Rated, to Convert Hinged Doors to Self Closing Doors - Black

This product does exactly what it says. It was easy to install. It works perfectly. If you have a very heavy door, it may not slam and close the lock but on normal internal basement or bedroom doors it’s perfect. I tried lots of other products and this one was simplicity itself.

Good it works and closes the door but be careful if you have small kids my son trapped his finger in the door within about 2 hours of me installing it...

I have a heater in my study and I like to keep the door closed in Winter to retain the heat. We self-installed this door closer (just a few self-tapping screws) and now my door closes automatically! We wound the door closer a couple of turns to give it sufficient strength to close the door since there is some friction between the door and the carpet below. In fact, when I want to keep the door fully open, I just open the door to about 90º and the friction keeps the door open permanently. The 'arm' can be unscrewed, so my plan in Summer is to deactivate the door closer.

Funciona super bien, y muy facil de instalar. Ya 6 meses con el y va perfecto.

Does not have the strength to fully close the light weight hollow interior door even though I had maxed out the spring force adjustment, although this was sufficient for the purpose I needed. I also installed the closer at the same level as the door handle, with the thought it will more evenly apply the closing force across the door to help it close reliably compare to mounting the closer at the top of the door. I was looking for the door closer that is mounted internally in the door jam as used with the heavier metal fire-rated door from the garage to the house, however it is more expensive and more involved to install, so this lower cost and easier to install door closer fits the need of this application.
