Every easy to install and operate, with little modification it can be mounted to a janus 3100 seris door ( 8x20) wind rated door , only negative it only comes with 2 remotes and having a hard to find a unverisal remotes to work with this motor . Overall for price and functionality beats spending 1300 on a lift master or the ata dominator

This is a great buy at $130 bucks. I had closed drum door so the stobs on opener didn’t fit my door but I knew that before ordering. I rented a hand crank material lift from Home Depot for 80 bucks just to be safe, I highly recommend this on bigger doors. Mine are 12x12. Tighten left side saddle down tight on door, remove left saddle and chain drive lift door and then I took the bracket off the wall to get it out of my way completely. Remove saddle and chain drive. I was able to use the sprocket bolt holes to mount a pice of 2x2 aluminum tubing to fit between the stobs I cut the tubing down to 1-3/4 x2”. The 2” fits right between the stobs. I also cut about an inch off the stobs to make everything fit back where I could put the brackets back in the same spot. I had this for 2 weeks procrastinating because I wasn’t sure what I was doing. I hope this helps someone else the people saying it’s doesn’t fit theirs we’re in the same boat as me with the closed drum, but it’s really easy to make it work and you will have the least expensive roll door opener around. Companies around me quoted 800-1200 to come do it and I did it for under $220. You can too. Rent the lift!

I love this opener easy to install. I recommend to install the opener on the left side of the roll up door so you don't have to mess with the spring settings. The first unit I installed on the right side took me almost, all day to get it working. But on the left side I was done in under four hours. I had to add 1 inch by 6 inch nipple to the doors to give me the room to mount the opener.

This model is designed to fit open roller door drums. For closed drum style some modification is required. You'll need to fab, or find a 'U' shaped metal bracket, cut to fit, and fasten to the closed drum plate. I used a 1 x 3/8" bolt and lock washer to fasten the bracket to an available threaded opening in the drum. Cut the two plastic legs down on the Vevor roller to fit the bracket. The bracket fits between the legs. You may need to cut a space for the cord to fit, depending on the wall mounted bracket. If your door has a smaller diameter main shaft, simply use a piece of pvc to fill the gap. The pics should give a pretty good idea of what needs to be done. (Don't try this if you're not real handy with modifying things to work...) After modification and installation the Vevor 800 N roller door closer worked perfectly! It is very quiet and smooth. Highly recommended!

Works really well on my 9'x12' Ideal roll-up door. Did have to make a mounting bracket for the motor since the Ideal brand door has closed ends on the drum.

Had a metal building erected with an 8X10 rollup door. Had to lengthen the main shaft of the door and drill holes in the drum. The opener is smooth and quiet. Would be nice if it came with a wall button and remotes that attach to your vehicle visor. The light is not much.

I am using the opener on an Asta 9' x 9' rollup door. The opener works smoothly and quietly. I plan to purchase another one for the other garage door in my shop. I do wish they had someone write the instructions who had a good understanding of English. They are a little hard to understand. I had to cut approximately 1" off the driving lugs and 3d printed a tube to adapt the OD of the door shaft to the ID of the opener. I also custom fabricated a mount for the opener. I don't recommend a DIY installation unless you have some fabrication skills. Overall, I am very pleased with the product.

Trabajan excelente necesito las instrucciones en español siempre tengo que soldar una extensión al eje central del rolling door para su adaptación ya que el tubo es corto y hacer ciertos arreglos a la base triangular

The operator operates the door up and down however I can not adjust the limit points. Also can not set the forces level using the instruction procedure. Have request a replacement

I wasn't sure that this was going to work for my application. I only had about 1 to 1 1/4 inch of my pipe available between my door and bracket. With 1 1/4 inch square tubing and modifying the spokes in the drum of my door it worked. It wasn't too difficult to do by myself. Once I figured one of them out my second door was easier. It has plenty of power to move 10x10 doors.
