Prime-Line Products KC10HD Safety Spring Door Closer, 4-1/4 in, Diecast Construction, White, Non-Handed

I bought this door closer expecting a smooth, soft-closing action, but it was very disappointing. Despite adjusting it, the door closes too abruptly and doesn't provide the soft close I was looking for. The spring mechanism feels harsh, making it noisy and unpleasant to use. If you're specifically after a soft-closing door closer, I would not recommend this product. It may work as a basic self-closing mechanism, but it certainly doesn't deliver a smooth or gentle closing experience.

Es discreto, funciona bien la diferencia con los brazos es que este azota la puerta. Al poco tiempo comenzó a rechinar pero con un poco de wd40 se le quitó y hasta el momento sigue funcionando perfecto. Se puede ajustar la tensión (fuerza) para el cierre de la puerta.

I tried some spring hinges to shut a door, but the springs hinged couldn't provide enough force to latch the door. So I tried this Safety Spring Door Closer and it works and works well. The door latches every time. It was easy to install.

Does what I bought it to do.. that is 5 stars in my books. Easy install too

This door closer appears to be somewhat coarse. The paintwork in the screw holes were coming off even though it was new (see picture). The threads for the closing arms also had some paint stripped off. As the closer is of metal construction paint may, depending on the finishing process used, come off quite easily. It was easy enough to fasten, but I was missing one plastic plug for the retaining screws (see picture) Finally, this closer is very noisy. When closing or opening the door, it emits a loud creaking noise. Measured with my phone, the noise levels in the room rose from 40+dB to 60+dB. (video attached). If you are looking to close a door inside your home, I would give this a miss. The common overhead door closer (while more expensive and more involved to install) is much quieter. However for applications where noise is not an issue, this closer works as described and is quite easy to install. There appears to be no fine adjustments to the closing rate. You can only select to put the closing arm into the available holes. Amendment - May 2021 Some time after posting the above review, I found some other reviewers who dismantled the unit and added lithium grease to the spring inside. Did this and after some time the closing noise is nearly inaudible.
