8ft Garage doors/opener

I am looking at possibly replacing the garage doors in a new house. The doors are standard width, but they are 8ft.

The existing openers are Chamberlain BW0777 1/2 HP models.

Many of the openers I have looked at say they are only good for 7ft doors.

Is there any rule of thumb to determine if an opener is sufficient or do I have to dig up the info on each door?

Also, on some units that info is easy to find and on others it is very difficult.

Thanks!

Sorry! - I might have read your post too fast! :)
If the doors are 8 ft. high -
you should try to find an opener that is suitable.
It has to do with the length of the "rail" -
screw, chain, etc...
(Me bad!) :)

Also, remember - when choosing the hp. for an opener -
the type of door and the weight of the door should be taken into consideration.
Solid wood doors - some steel doors can be very, heavy!

Most door opener manufactures will have an extra box with a piece of rail, chain, etc for the 8' rail.

Sears, liftmaster/ chamberlain are the only brands I recommend.
I told a guy once standing in line at Menards to put the Stanley he was purchasing back....he asked why.....I pointed at my shirt...

Just to clarify the doors are not being replaced just the openers (maybe). Why? They are old and the remotes and a couple of the sensors are missing. We also want an external keypad.

We are also investigating working with what we have and replacing the missing items.

Thanks again for all the responses!

I am referring to the opener only.
