will the 3800m liftmaster lift a 12ft high door

Yes. I have a 14 foot door. Has the power if the springs are adjusted so you can lift it with approx 30 lbs of lift force.

Some garage doors are taller than others. This opener is designed for a lower door. My doors are 8 feet and considered high. I purchased 2 of these for my 8 foot doors. They work beautifully but I do lose about 10 inches of overhead clearance when they are fully open. It's not a deal breaker for me because I'm not driving an SUV or some other taller vehicle. You can buy an extension to accommodate a taller door but for me these are perfectly fine. The bottom line is if you purchase this for an 8 foot door your door will only open about 90% unless you get the extension. My 8 foot door opens just over 7 feet.

Depends on weight of door. I found I could contact manufacturer directly and they would size lifts correctly for me.

Yes, the lift can elevate from 1 inch to at least 9 inches. It is very convenient and adjusts instantly if you need it low or high. I would highly recommend it!

I would question how stable the lift would be at that height. I used mine on a standard 8 foot ceiling without any help from anyone. Sorry, I can't be of more help.

I don't think that would work since it sits up high. The door could not be opened.

yes. the load rating on the tubing the lift is made of is 400 lbs+..the lift can handle the 5/8 x 12', just make sure you use the roller stop leg so that the lift doesn't get away from you while you load it

If the doors are adjusted correctly they would work fine. The doors have to be balanced and the springs need to be adjusted so you can lift the doors with almost no effort. Its a good idea to download the instructions for the Liftmaster website before buying.

Not sure man, I haven't puller it up that high. But I will tell you that I used it to pull the cab off my 29 model A frame. Had the bottom of the frame about 4-1/2 feet off the ground. It works well.

I would think so. It will go up high. I have 12' ceilings and I use it to run along the molding areas up high.

Yes it could however the lift hight is limited and the rails that do the lifting are about 12" wide

Thank you for you interest in doing business with us!To be absolutely sure we contacted the manufacture for you. They confirmed that this RE3700 will work with a 2 inch lift just fine. Also, this control arm is just a 1/4" longer than your factory control arm. We hope we can earn your business on this product and many more in the future. Thanks again! PerryACME1-866-992-3669

Yes it will. I'd recommend a level or small lift with the lower offset though.

Do a google search of "Liftmaster 8500 manual" and look at page 3 for all the pre-installation requirements. I found this link: http://www.liftmaster.com/CatalogResourcesV3/en-us/shared/files/tucmanuals/114A4565.pdf On that page it gives this answer: The torsion bar must extend at least 1-5 inches (2.5-12 cm) past the bearing plate. This may vary depending on your installation requirements.

Don't recall the specs. But the lifts are stronger than originals on vehicle. Should support ladder that came with vehicle.

Yes it will work on a 24" tall rail. I have installed on a taller rail. All you need to worry about is the cable rubbing on the rail itself. I recommend letting the end of the lift hang an inch or so off the end of your rail if possible. This will help prevent the cable from rubbing on the rail in the down position. I would do a test trial before "permanently" securing it. I hope this advice is helpful. I could go in to further detail if necessary or you can call the manufacturer.
