Will this prevent a heavy door from slamming all the way open? Our door opens and swings all the way hitting the siding with any type of wind.

It is adjustable for all types of winds except hurricanes, and for heavy doors, you can make it hard and soft as you want the adjustment, I recommend it.

Can this stop the door from opening beyond 90 degrees?

I think the door can be opened up to 110 degrees

Does it help the door close slower as well? We have a heavy door and it slams. We are looking for something that helps close without slamming.

Yes, the speed for closing and latching door can be adjusted, and won't make the door slam. It applies to the door weight between 45-60 kg (99lb-132lb), and if you need the door hold open, the door and jamb should be on the same plane or not on the same plane but within 5 cm. Thank you.

Can this opener be installed on the inside of a door that opens outward?

I believe it can, you would have to mount the cylinder to the door

Brilliant!

This arrived today and I fitted it this afternoon. It’s BRILLIANT! The instructions and particularly the paper templates make it pretty simple. It certainly works excellently, closing the door firmly without slamming. I recommend it wholeheartedly.

Excellent door closer, easy to install.

This door closer does the job, the instructions for installation are very clear and they have templates for all possible configurations. Just 4 screws needed for the main unit and 2 for the arm. There are different sized screws included, and it even includes the drill bit you need for the holes. Installation took about 14 minutes to mark up the template, drill the holes, screw it in and adjust it. There are two adjusters for closing speed - one for the last 20 degrees or so and one for the rest. The unit is good quality aluminium body and steel arms, it should last years.

NOT idiot proof

Yes, there is a big warning in the instructions but if you unscrew an adjustments screw too far it will pop out and spray the hydraulic oil everywhere. Attempted to refill with similar oil but I guess I knew that was never going to work. Good templates included and very easy to fit. Idiot.

Endlich ist die Tür zu!

Schrauben mit ordentlichen Düberln nehmen! Montage zur Zweit ist ein Vorteil (habe es alleine gemacht), weil es ein bisschen kompliziert ist ihn festzuhalten, markiere wo zum Bohren etc....aber es geht. Mein Eingangstür, 90 cm schwere Holztür von 1960, schliesst nun endlich....weil meine Tochter tut es nicht!

Does the job perfectly

Following a house inspection, it was urgent we address the recommendation to install a door closer on the door from the house leading to the garage. We received it next day, installed it with no problem thanks to the clear instructions provided. I recommend it.
