Question: I have a very low overhead door.  The opener I have now is almost flush with the ceiling. Does anyone know how close this one can be to the ceiling?
Document: I've owned this product for almost two years now, and its performed well. My application was unique, having very little space between the ceiling and door (5"). Also the door spring sits over top of the door where you are supposed to mount the rail. I had to modify a bracket and mount the rail and motor very close to the ceiling.
Installation took about 6 hours, (one person) and it went in without a hitch. It is quieter than the other garage door opener that came with the house. (two car garage-house came with one opener) Only thing extra needed, was a length of angle with the holes in it to mount it to the ceiling. Don't let the low cost fool you, this opener will do the trick handily.
I checked around and this opener was the best price for what you are getting in the low cost end of openers. Since I was using it to replace one that was about 20 years old, the install was pretty easy. The one thing different on this was the safety light beams that my old one didn't have. It took way longer to run the wires for them than it did to bolt them to the bottom of the door rails. overall, I would buy another one.
my dad's purchasing another one (for their second garage door) in just a few minutes.i just wanted to let some wary buyers know that mine came on time.
This unit replaced a failed Overhead Door unit. The installation was relatively easy and the unit works as advertised. With a couple of months experience with Chamberlain, I would purchase another one.
Replaced my old opener only because I just couldnt seem to find any replacement remotes for it and also because it did not have the security sensors which prevent the door from closing if anyone is standing in its path. The instructions that came with it left a little to be desired... but once I got the hang of it and made a fresh start, I got it done in about 3 - 4 hours.
I dont have to open and close the garage door manually anymore!! So far s good - its 2wks old now
We needed to replace our 20-year-old garage door opener when the motor burned out, and my husband did some research and chose this one.The true test was when he had to install it - he is fairly handy, but not an expert, so if he could do it, I think any handy person would be able to.
The wall opener has a nice, large pad so it is easy to find in a dark garage.Quiet factor is ok. The opener motor doesn't seem to be any quieter or louder than any other basic Chamberlain unit we've installed.Price-wise, this unit is in line with other similarly featured door openers. I plan to purchase another one for another single garage door. Recommended.
Just a real economical door opener, that works like a champ! I have installed dozens of these where I live and work as a &#34;Handy Man&#34;. I thought I would take the time to review it. Each one has worked flawlessly out of the box. Never any missing parts, always goes smooth as silk. Every thing to do a professional installation. I usually toss the copper staples for the wiring and use my T-25 staple gun, looks better.
