ANSWER: Which one would you recommend? This will be used in my residential garage and not get a ton of use. by brad l a
ANSWER: Yes it will work, but I would recommend a bigger unit for a door that size. That is a lot of weight for the 3950. I think one of the commercial models would be a better fit. by Robert O a
QUESTION: Hello the shaft on my door is much smaller hen the hole in the dead shaft sprocket. How exact does the sprocket have to be centered and whats the easiest way to do it? by Arnie L 8/16/2015
ANSWER: I would first get an accurate measurement of your dead shaft diameter, then call Northshore to see if they make a sprocket in that size. If not, you will have to have a machine shop make an adapter for you. by Robert O a
ANSWER: I reread your question. It's pretty simple attaching the sprocket to the drum. It must be centered on the drum. etween the pre drilled wholes in my garage door drum and the sprocket holes it lined up and centered easily. by Brian D a
ANSWER: I installed the opener myself. It doesn't matter if the door shaft is narrower, as long as the sprocket will fit through it. The sprocket attaches to the hub of the opener which the door rolls up on. Hope this helps. by Brian D a
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: from what I remember I think it will by Matt 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
