QUESTION: What size shaft is this setup for? Will it work with a 1-5/16 shaft? by Darin W 7/22/2015
ANSWER: Mine have a pipe going through it that did not turn and the ends of the door drum turned on the pipe that was stationary. As you can see in the instructions it will work with both a dead axle and a live axle so I would say that it would work with yours because they give you spacers for spacers are 3 spacers to hold the gear to the end of the drum it worked really well. by Mariel K a

ANSWER: My door has the same size shaft and the sprocket did fit the shaft. by Fred W a
ANSWER: Yes it should fit jut fine, it comes with two sprockets one for mounting to the shaft and one for the drum depending on what type of door you have. The measurement on the shaft sprocket is 1 5/16 ID. I install two of them and it was a walk in the park. Even thou the company were the doors came from said I had the wrong type of door and it was not made for an opener. They work just fine ever time I hit the button. by David G a
QUESTION: This door opener was recommended to me by a sales representative from DBCI self-storage doors for the model 650. He assured me it would work. Can you confirms this? Many thanks. by Gerald M 7/13/2015
ANSWER: Yes this door opener works excellent I would buy another one in a heartbeat by ronald m a
ANSWER: Hi Gerald,<br />I'm using the same unit on a roll up door ten wide and fourteen feet tall. It is set to only open eight feet to save time when we close the door and save wear and tear on door and unit. I have purchased two units and will use this unit to replace my older garage door openers when they fail. I like the clean look they give to a garage.<br /><br />Thanks Roger L by Roger L a
ANSWER: I have not had any problem with mine at all. However, I had a professional garage door company install it. I use to have a chain pull opener. I really like this motorized opener, I also got remote controls. This unit is well worth the money. by Nora W a
ANSWER: I don't know what a model 650 door is, but I have two of these openers on my roll up garage doors that are 8' by 9' and they both work great. I am planning to buy two more for another building I am currently constructing. by Robert O a
ANSWER: We have two roll up doors in our building that are much like those found in self storage units - though I suspect ours may be of a heavier gauge. Both went in quickly and have worked great for a year or more. The openers are a great price from this vendor and dodo dry is quick; but if you want the remote control "clicker" , you will find those much cheaper on e-bay. by Michael C a
QUESTION: Does the 3950 allow Up / Down / Stop, so that you can open/close the door and stop it at any point? E.G., to leave the door open 6" at the bottom for air flow, or for the cats to come/go, but not the neighborhood teenagers. by Daniel P 3/9/2015
ANSWER: You can open or close the door as little or as much as you want. I also ordered two remote controls with my opener, and they work just fine also to do what you want to do with the opener. by Nora W a
ANSWER: Yes. You can open close and stop at any point of operation. You can also use remotes and the keypad the same way. by dan w a
ANSWER: Yes the 3950 has all three functions up, down & stop .<br />This operator is a great unit that very quiet operation .<br />Very dependable unit.<br />I have 3 of these and love them. by Byron L a
ANSWER: Yes, you can do that. It works just like a standard garage door opener. One push to open. Another push stops it on the way up. On the way down, a push of the button reverses the door and sends it back up; but another push stops it again. We have two of these and they are great. We also have several two-button remotes and can operate either door independently from the cars or the golf cart just like standard garage doors. by Michael C a
QUESTION: Will the factory installed remote control in my vehicle work with this opener? by Dan B 9/14/2014
ANSWER: I did not program my openers to my vehicle. I would think they would be compatible but not sure. In the past I have programmed vehicles 2010 Tahoe and 2008 king ranch to gate openers that were purchased from tractor supply. From what I understand these are a newer version of the old chamberlain openers anyway. by Tommy R a
ANSWER: Yes it will. Operator has logic programming same as other operators by kevin m a
