Commercial Full Cover Door Closer in Aluminum with Adjustable Spring Tension - Sizes 2-6

After about 12 months, the door now has leaked oil and hydraulics is completely gone, slamming the door every time it's open as I have a heavy metal door. I would've gladly paid a lot more to have something that works for years instead of one year as the install takes a couple of hours and two person.Have no clue how to contact support or what the manufacturers website even is.

I bought this door closer 11 months ago and it has already started leaking oil and quit working. It is used in my office at a door that is not heavily used. I AM VERY DISAPPOINTED.

I have had this for 7 1/2 years performs really well.
