Yes! This unit has an auto reverse safety system installed. There are two trip circuits that will be installed at the bottom of your garage door (not on the door itself) on the garage wall. If the light beams are tripped, the door's operation will be ceased, and automatic reversal of the chain drive will occur.

Yes! This unit has an auto reverse safety system installed. There are two trip circuits that will be installed at the bottom of your garage door (not on the door itself) on the garage wall. If the light beams are tripped, the door's operation will be ceased, and automatic reversal of the chain drive will occur. This means that if the door is closing, and the light beam gets interrupted, the door will stop and return to the full open position. When the door reaches the full open position, you can re-trigger the door to close by simply pressing the correct button on your remote. Your pets have nothing to fear. Read Less

Answer: 
Should be a red handle attached to a rope hanging down near the center of the door. Pull down and back. Should detach the drive from the door allowing it to "free wheel". To reattach pull down and forward. You kind of have to get a feel for it. I would recommend getting used to it before you need it.

Thank you for your question. If the power goes out there is a manual disconnect built into the garage door opener. Pulling down on the disconnect handle will all the garage door opener to be manual opened.
You may be interested in a battery back up system. These garage door openers will allow the remotes to continue to open and close your garage door even in the event of a power outage.

No, you don't have to use the keyless entry device. I didn't and my garage door works perfectly. The garage door opener company provides a third remote (wired), that is permanently installed on a wall for this purpose. There is really no need to install the keyless entry device.

Answer: 
All door openers at any "box" store will open 7' doors only. To open an 8' high garage door you need to purchase an 8' extension kit. They are sold in the same department as the openers and cost about 35-50 dollars more.

It does work on an 8 foot door, assuming the door is not too heavy. I suggest you contact the company directly to ask about weight requirements. They may suggest you up the hp to 3/4, but again, I think it depends more on the weight verses the size.

Rated 4.2 out of 5 by 294 reviewers.
Rated 3.0 out of 5.0 by So Far So Good... I am quite pleased with my opener. I originally had a Chamberlain opener and it lasted for over a decade. This model is quiet and has many features. However, I was displeased with the fact that my local Home Depot in Eastvale, CA, wanted to charge me over 200.00 to install it, which I thought was outrageous. The installation cost was more than the actual price of the product. Insane!!! It makes you consider that next time when purchasing an item from Home Depot. I hired an outside installer who charged 100.00 and it only took them 1 hour to install. They did an excellent job and I could not be more happy. May 3, 2016
Rated 1.0 out of 5.0 by Installation Opener may be fine. I don't know since I'm on day 10 of waiting to be called for installation. For a new build that may be fine. For a replacement that is horrible service. Don't buy online and have the installer bring it. Buy it yourself and bring it home. Company claimed they just got the order Monday (Day 7) so HD held it for a week. I could have hung it myself in the time I took to follow-up on my order. May 4, 2016
Rated 5.0 out of 5.0 by Good Product, Easy Install, Nice Features I have two of these installed now. One has been in service for over a year now, the other I installed last month. Works great. Good price for the feature set. No problems with the installation or operation of either unit. I haven't yet looked into the wireless home automation stuff on it, we have no need of it. So I cannot speak to that. Feels like it is very solid-built with quality parts. May 3, 2016
Rated 5.0 out of 5.0 by Excellent product for the money I had an installer set this up so I cannot speak to the ease of installation, but he was the one who told me to buy this brand. It works well. May 10, 2016
Rated 5.0 out of 5.0 by garage door opener it working find and I want to say the men who installed it was great and knew what they doing..you are lucked to have a great in stallers May 10, 2016
Rated 5.0 out of 5.0 by Excellent quality and price As an electrician, I've provided outlets for numerous openers, but this is the first one I ever installed and on my own home. I was concerned about the door -- an older, wooden sectional, but trimming about an inch and a half provided enough clearance. I also used Chamberlain's excellent technical support, . First to correct my assembly mistake and second, to get help to program the door travel. Both times solved my problem. The mistake involved installing the track upside down on the U bracket; how to disassemble without destroying either the track or the bracket. Excellent design and quality. March 25, 2016
Rated 5.0 out of 5.0 by great product, easy installation My husband and I installed this ourselves in 2.5 hrs. We had an old liftmaster and were able to use most of the previous parts which made it much easier. I really like the two lights and the keyless entry. May 1, 2016
Rated 4.0 out of 5.0 by Good value with all the features included I wish they included the hanger bracket for finished garage ceilings. Current homes now are usually finished with drywall and a main hanger bracket should be included as standard assembly items. April 26, 2016
