Works great but a shame to trash chain that was purchased in the box
Easy addon if your garage is an 8 FOOT GARAGE. Parts inside this box fit perfect to the parts in the garage door box.It is a SHAME that I had to throw away the chain that came with the garage door opener. Seems like a waste. Not a friendly green option. CHAMBERLAIN should have a free return option and maybe even a small credit. No where is it obvious that you need this kit if you garage is an 8 foot garage door. Stumbled onto it when reading the comments from previous Amazonians who purchased the garage door itself.

They recommended this opener rather than a cheaper model that
I called Chamberlain to ask about a replacement when my previous Lift Master/Chamberlain garage door opener failed after 20 years of service. They recommended this opener rather than a cheaper model that, on paper, should have worked. Chamberlain's customer service was excellent, by the way.This opener went up and worked like a champ first time with only one change to my existing mount points. I had to purchase a length extension because the length of the opener out of the box was too short, even though I was pretty careful to measure everything and compare to what the manufacturer's specs indicated were necessary. After I got the extension added to the opener, which was almost too easy, I moved my mounting point back about three inches from the previous location.I am very well satisfied with this product.

Worked great!
I have to wonder why the company does not sell a 7 ft. model and an 8 ft. model. Lots of extra parts were purchased just to get the extension. Anyone need a brand new in the box chain for a seven-foot door? Just a waste of resources.

Good product.
The extension worked as needed. Easy to install and include the longer chain needed. This was available on Amazon when the same item was on back order at Lowes

Works for some Craftsman Chain Drive openers
I bought this in hopes it would work with my Craftsman 1/2 hp Model: 54985 . Turns out it fit fine. It was the exact same tube and chain type. I used it for a custom vertical mount to open roll up doors. Worked great. Going to order a second because its so inexpensive, to have as a spare chain.

Fit perfectly and works as it should.

Extension was part of the package but didn’t need it
This part was included in the package I bought but I didn’t need it. The package was still cheaper than buying the parts separately.
