I'm wanting to install a garage door?

[glossgaragedoors]

I purchased a new commercial garage door repair Calgary , I have a belt 3/4hp opener and i was opening box and im lost, I read the instructions, just still lost kinda on how it hooks to the actual garage door.
Do i have to purchase something else to work with this that doesnt come with it ?
There is no existing garage door so this is why im lost on this issue,
Thanks

It's interesting what I saw there...

I am such a person that, for me, garage means a lot. It's where I can stay alone and work in my car or have some fun with friends. I like to call it a chill zone. A private one, without my wife. LOL. So, I can advise to modernize it by installing there a business door chime. In this way only you will have access there. You will see on the screen who wants to come in and out. And, it's still looking very sick. I installed such one, and I am glad. Now my garage is looking like a sick house. I think that this is very worth it.
