Will this be able to move a 15 pound Aluminum door (not slide, but full 15 pound load)? If not, what is max load?

No, it will not. This is a little tiny stepper motor designed mostly for 3D printers or small cnc machines.

if you run it with a 2 amps per channel , 12 volt stepper motor driver , you have the [ F=Ma] to drive it ... but very likly it will get the VMOSFET's quite hot . the motor itself will do the job , its the driver that you will " let the smoke out " most likly ... frankly speaking , you can not stop the shaft from turning in your fingers ... its likly stronger than a 3 year old with a cresent wrench ... the issue really is... under the load your suggesting.. will the motor driver over heat and fail .

It's all a matter of mechanical advantage... Said Archimedes: "Give me a lever long enough, and the place to stand, and I shall move the earth"The rating of the motor is 57 ounce-inches. This means that if you have a pulley with a 1 inch radius (2 inch diameter) attached to the shaft, then at maximum current it will be able to support a load of 57 ounces on a string hanging from the pulley. In theory, if you wound a string directly around the shaft of the motor, this would give you a radius of approximately 3/16" which would require 45 oz-in of torque to lift 15 pounds (barely within the capabilities of this motor).

I'm not sure. I have mine on a regular door with a brutal B-ready, and it works great! I was afraid it was going to be too heavy or not be sturdy, but I was very impressed!

Gosh, that's tricky! I'm not sure but this little guy has rubber grips so on my slippery metal door casing it holds a really heavy door open! It's inexpensive enough to give it a try!

Yes, it will not move an inch! I love it. Just wish it wasn't so overpriced, not to mention the shipping!

Yes it will work with a 15" opening as long as you aren't talking about the dimensions of the outside door . I have a 16 1/2" oppening and in I have wiggle room left over (when measuring what you will need to pull through the door it is approximately 14" for the basket and the sliding hardware. You will also have room left at the back of your base cabinet. Mine is 44" and I could still fit an additional tray behind it. Hope this helps. (Oops, wrong account was opened.

Yes this weighs about 4 pounds. It will easily hold any door open unless the door has a closure which pulls the door shut. In that case only a traditional door stop would work.

Not sure this will move with the door. Rubber on multiple sides. Perfect for keep a door open. I do use it on a carpeted floor but really wanted something to keep the door open.

I have a double width garage door, which is quite heavy. I am sure, although I never actually weighed the four sections, that they weigh over 150 lbs. together. These rollers work just fine.

I have a solid core (pressboard) door measuring 16 feet across. It's 30 years old. I assume that it's heavier than normal and I don't have any issues.

It takes about 10 lbs of pull to make my door release from the magnetic door stop. That is added to a large spring's tension trying to close it. So if you can measure the force trying to close your door, and it is less than say 8-10 lbs, might just work. You could always buy one, try it. Amazon often has "used" units a a nice discount.

I wouldn't use this particular switch on a sliding door. The reason is because it is spring-loaded, and it is likely that it would just push your sliding door open rather than keep the switch in the "off" position.

Of course it will work - As long as you want to use it to "pull" the door closed. If you want to have it "pushed", that's a different product.

I have used this to move a 1300 pound trailer (Pace 6x12 enclosed Trailer) It worked pretty well and was easy to maneuver. Never leave the Trailer connected to this unit. If the trailer does move this unit can not withstand the force. We made that mistake. We like the product and its worth the money.

I feel one would work for this size of door. I have a long narrow door, 15x40, and the lift is great plenty! I have considered taking one off to see how it would work.

Weight limit for this door is 25 lbs. You can check their website for additional info.

the weight limit on these ramps say that it can hold the weight...I think that it may be pushing it, they are light weight welded aluminum at 15 lbs. each ramp. If you are looking for something that will hold up to continuous use you may want to look further. If these are to be used not so often then these are right for you...good luck with your purchase ....whatever it may be....

My door is about 50 lbs or so. It is a 7 foot door and thicker than normal (1 5/8") so it is robust! A shorter door, same weight, might work.
