COMMENT: This is a great device at a great price. This vendor had the lower price for the unit and for shipping. Vendor answered on first ring and was responsive to questions. The first unit works great; and we have just ordered a second one for another door. by Michael C 3/28/2014
COMMENT: Becasue it comes with the sprockets by Nick R 2/28/2014
QUESTION: We have a Wayne Dalton roll up door with the manual chain lift. Will the 3950 replace the chain lift The chain lift actually drives a large sprocket that is already on the jackshaft. I can supply a picture if needed. by Paul B 3/6/2014
ANSWER: Leave the chain in place so you can still operate the door manually just in case there's a power outage or for some reason your liftmaster malfunctions. My jack shaft was long enough to mount the liftmaster on the opposite end from the chain sprocket. Make sure to order the mounting brackett because it's well worth the money. If you would like to provide me with your cell number I would be more than happy to forward some photos by Willie K a
ANSWER: Yes, but you will most likely have to change the sprocket that is already on the door you have with the one that comes with the 3950 in order to make the gearing right. It may run too fast or too slow if the gearing ratio is not correct. by Robert O a

QUESTION: I have 10'x10' roll up door,do I need to release the tension on the shaftA Amazon customer said a mounting bracket,chain guard and extension tube is needed.Is this true and how much are theyI have installed garage openers on sectional overhead doors,will I be able to install this myself or do I need to hire a professional? by Bruce R 12/9/2013
ANSWER: Hello, We installed the openers with very little difficulty. There were no additional parts to purchase. The only modification we made was to drill the hole on the gear where it attaches to the shaft out a little to accept a 1/4" bolt instead of the cotter pin that was supplied. Do not release the spring for any reason, as this will remove all assist from the door and the motor will not be able to lift it open. The instructions say to engage the opener after it is installed is to cycle the motor. This will not engage, I found that by pulling on the release cord till I heard a second click and then release it slowly it fully engaged the motor. the opener works great. Hope this helps. by Sandra Z a
ANSWER: Not sure what you mean by "release the tension". If you have a torsion bar on your roll up door then the 3950 is not the correct model. You would need the 3800. If you are talking about just the spring tension on the roll up assist mechanism, then no, there is no adjustment required.<br /><br />I recommend the mounting bracket. It will make installation much easier. You don't need the chain guard. You should not need an extension tube either. If you do, then again this is not the correct model door opener for you.<br /><br />I have done several sectional door openers, but never a roll up door opener until this one. I did not have any trouble. It is actually easier than the section door opener because there is no track bar for the chain to ride on. The opener connects directly to the jack shaft via a short chain and two sprockets.<br /><br />Make sure you know if your door is live shaft or dead shaft. It makes a difference on how and where you connect the upper sprocket. by Robert O a
ANSWER: No need to release the tension. I thought you only needed a guard if the motor was mounted under a certain height. I did not need an extension tube, the gear fit the shaft - the shaft only needs to be 1 - 1.5 inches long. It was easy to install - I did it by myself but 2 people would be best. by Kim T a
