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.

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.

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 4.0 out of 5.0 by Good value This is a very good opener for what you pay. Chamberlain is one of the best out there and this unit is no different. It is easy to install and the keypad and remotes are easy to set up as well. I was pleasantly surprised by how quiet it is, especially considering it was listed as middle of the road for noise. July 14, 2016
Rated 4.0 out of 5.0 by Door opener Works great. Easy replacement install. New install would be even easier. Definitely need two people at times. Not as quite as I was expecting with belt drive. But not abig deal. Garage is not attached to house. July 13, 2016
Rated 5.0 out of 5.0 by great buy this opener had all the accessories I wanted and went right in July 5, 2016
Rated 5.0 out of 5.0 by Chamberlain took care of me when I had a problem I installed a Chamberlain 1/2 horsepower chain Drive 2 years ago when my old garage door opener gave up the ghost. it has been working great until a power failure. Strange as it may seem the remote worked but the wired door switch would not work. I called the Chamberlain hot line and she recommended several steps to take to be sure it was the switch. I checked it out and it was definitely the switch. Since I had a surge protector on the power outlet and it was less than the 2 year warranty, they sent a replacement switch right away, mean time I just used the remote to open and close the door. i replaced the door switch and it works great now.. They did a great job on he warranty replacement. DC June 3, 2016
Rated 4.0 out of 5.0 by nice find It was easy to install, and I only had to replace the main box, and wall control. The only problem with this product was instructions for reprogramming the remotes . One of my neighbors had the same one. They left in on factory settings like I did. When they left my door wood open. When they came back it opened once again. Reading the directions all three of ushad a problem with it. It needed to Specify to use the actual box that was installed to program it. Shows a picture of the wall Remote. So that was confusing. Works great now that we figure that out. Hope this helps you June 7, 2016
Rated 5.0 out of 5.0 by Smooth process start to finish Installation was super fast and done well. I would definitely recommend having them install it for you July 12, 2016
Rated 5.0 out of 5.0 by Great purchase so far!!! Device was installed by professional. There was an additional cost. June 28, 2016
Rated 1.0 out of 5.0 by Worst purchase ever, including lousy customer support from the company. Never Chamberlain Purchased this garage door opener 3 weeks ago, got installed by a professional. Noticed the sensor stopped working, so garage door does not close. First I tried aligning sensors but green light does not come on. Called help line, only to be put on hold for more than 30-40 mins on 3 different occasions before I could get some one on line. The rep tells me I am probably not aligning sensor properly (the light came on flasing green briefly as I loosened wingnut and took sensor out of bracket, but then never turned on again after 15 mins of maneuvering, whatsoever). Then he asks me to cut the wires to sensor to test before they can determine if its faulty to send replacement (per warranty). I said I was not going to go thro' troubleshooting but just going to call the person who installed and if the sensor was deemed faulty would they cover the parts cost. He says no, and he seemed pretty rude as well. The overall quality of products and customer service of this company sucks !! June 28, 2016
