This deal was posted several days ago at 159, found it on clearance at my local store for 89.99 so posting again with revised price reduction. My store had 2 remaining. Good luck! Original "black Friday" tag was listed at 199 or something.

guessing I'd need a little bigger, maybe 3/4 HP for a 2 car garage door?

Very interested in this - how do I interpret BS saying there are 7 in stock "clearance" but HD.com telling me there are none in stock (at the same store)?

Also, this is a 1/2 HP motor - would this be suitable for a single, 8 foot insulated door?

I am closing on a house in a few weeks and anticipate changing out the currently banged up garage doors for insulated ones, and also changing out the shit craftsman openers they currently have.

I got mine for a single garage in my new house, 1/2 hp should not be an issue unless you get something really heavy like "wood" doors. 8 ft length may require an additional extension though, that I'm not familiar with.

1/2 hp should* be okay but I'd say go with 3/4 hp to be safe. Weight of door, resistance from rust/age etc will all wear on the motor and having the extra power may help with smoother operation.

Take that with a grain of salt tho, that's the logic I followed for my 2 car garage door in my new house. I'm not expert Smilie

7 sounds like a worthy trip to home Depot if it's not a crazy drive lol. Mine showed 0 in stock and I found 2.

Standard 8 foot, single bay door - insulated, which means it will be a bit heavier.

I put in a Genie belt drive on my current, 8 foot DOUBLE door a couple years ago and it was pretty straightforward. I'll assume Chamberlain is comparable, the kit for the taller door amounted to a longer belt and a guide rail extension, nothing difficult

Wish it had the outdoor keypad instead of the camera. $50 more if purchased separately ☹️

Insulation matters less I think than core material of the door, but again I'm no expert. I can't imagine insulating any sort of modern "normal" steel door would increase weight my more than 15-20 lbs. It really shouldn't be a factor in the HP rating for openers. Natural wood doors on the other hand probably weigh a ton.

Curious tho - the genie you installed, did you have to get a rail extension? This one seems to come standard with 7ft rails and I thought that was pretty much the "default" expectation

I picked mine up at $160 d'oh last week. My local HD inventory said 0 instock but I discovered them on an endcap next to the GD section, there were about 8 or 9 left.

I'll swing by on the way home and play the game.... worst thing that happens is I waste 10 minutes. I need 2 not just 1 so my incentive for saving money is higher laugh out loud

My current GD I got on sale from HD as well, ironically it wasn't in the GD section - rather as I looked around for them, none in the typical clearance end caps, none in GD (not even a sticker as if they sold them), but there were a pile on a higher shelf over near the S4S wood. So, either they have a dumbass stock method, or someone was poorly stashing them for later purchase.

It's not ideal, but it is what it is. My biggest issue with the way the rail goes together is that the alignment isn't very "positive" meaning the extension just kind of sits in there with a wimpy screw in the top. When you tension the belt, it has to be tight enough so there's no backlash but too tight and it starts to bow the rail, and this is exacerbated when the opener kicks on (momentary compression force). Seems kind of lame to do it that way, frankly. It works though.
