Wright Products VH440 Medium Duty Hydraulic Closer, Aluminum

Now it slams the door almost all the way and starts to smooth the door closing at the very end.UPD: 9 months and door jamb bracket has gone... Poor, poor quality.

I used these hydraulic door closers on security door and they represent a big improvement over all the pneumatic types I have tried. There is no "bump" when the door closes; it is a very smooth close. In one case, I had to drill one new hole for the door bracket, but installation was easy as I used most of the mounting holes from the previous installation. About the only thing less than optimum is closing adjustment speed can only be done in 1/2 turns of the tube or barrel and sometimes it would be nice to be in-between to get the perfect close.

Lasted a month then leaked at the gasket and started to snap shut

One year of use before it started leaking hydraulic fluid onto my patio. I bought 2 and one is still working albeit on a door that is not used often.

easy enough to install, speed adjustment is done by popping out the pin holding it to the door and rotating it some number of half-turns or full turns, I like this better than other styles which require a screwdriver to adjust as this can be quickly changed when the cold weather comes and the screen is changed for glass.only reason i have not given it 5 stars is I have not had it long enough to know how reliable it will be.
