Ouvre-porte de garage VEVOR, télécommande 800 N Lift Force de 164 pieds,

il était défectueux dès la réception. et ensuite nous avons changé d'idée et opté pour un autre type de produit pour notre projet alors nous n'avions pas besoin de remplacement.

Fits the Leadvision roll up shed door

The opener arrived on time and seems to be good quality. Only time will tell how long it will last.

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!
