There are a couple of downsides however. First, some of the internal parts are made of plastic. After repeated opening and closing, combined with a few years, the plastic gets a bit brittle, and it's the part that fails. When it fails, they only come down on the side where the piston is. In all 6 of the ones we replaced, they all failed in the same place, essentially ensuring that they would only close on half of the door
The second downside is that they do need adjustment, and it seems to be more than just set it and forget it. You get it working with no issues, open and close it a dozen times, then it may (or may not) get sticky and not fully close.
Admittedly, they are used way more than an average homeowner, but for an industrial piece like this, it's disappointing that Pemko uses plastic for a couple of key stress points. I'd pay a few bucks more for one that was all metal.
