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.

I installed one on my 1950 series Janus roll up. minor 1"~ cut on the plastic driver assy and a 1" pipe nipple used as a spacer through the hub. i think i used a small piece of 2x2 steel square tubing for the door mount that the opener mates to.

The directions left a little to be desired, but once I got it installed, I could not be happier with the product. I will buy another one!

Great roller door opener! Easy to use and operate and program. My shed is now automatic which is very handy.

It took a bit to set the limits but once it was sorted it works well. The only downside is the remote range isn't all that good but it does work.

The lift arms don’t fit my 10’x10’ roll up shop door. Is there an adapter? Would love feed back. Over all it seems like a great addition for my shop and would order 2 more but need feed back
