Wiil this fit Craftsman 3/4 hp model # 139.53990 ?BPGDI

Answer

I found this rail kit easy to install with a wonderful set of instructions. Every thing works perfectly. I downloaded a Craftsman rail kit manual and a Chamberlain rail kit manual. They appear to be pretty much identical. My hunch is that the rail kits are interchangeable and the identical manuals tend to reinforce that.

will this rail work with a lift master 3265?

Answer

Liftmaster openers use a different rail than Chamberlain openers. This won't work for your Liftmaster.

What is the difference between 7710cb. And the 7710cb-p? I have a chamberlain 248735.

Hi Sam, the 7710CB will fit garages with a 7 ft-10 ft high door, whereas the 7710CB-P is made specifically for 10 ft high garage doors. Both kits will be compatible with all Chamberlain chain drive garage door openers (except heavy duty chain drive models C205 and C455).

I altered it to fit a roll up garage door. It was attached to the wall down to the floor. I first purchased a regular garage door opener and needed it longer to fit a 10 foot rollup. I had to cut one of the extensions to fit then shorten the chain. Works great.

The Chamberlain 10 ft. Chain Drive Rail Extension Kit is simple to install and works perfectly extending my Chamberlain Opener Rail to work with my 10 ft. door. Everything needed to extend the rail is included in the kit. Hardware still used in the assembly that are from the opener's set of hardware fit the extension rails perfectly. Once assembled the completed opener does not look modified in any way and works perfectly. I can't believe how easily it all fit together.

Love the ease of installation with the extension kit
This is the second one I have purchased and I love the ease of installation, especially with the extension kit. It also has performed to my expectations.

Love the price of this garage door opener.
I put this opener up in about 2 hours. It is priced right as always from Home Depot. They didn't have the extension kit, but they ordered it right from the store and it was delivered to my home with no shipping charges. It also shipped very quickly. It came with all the parts and went together very smooth. The performance is very quiet and I love it.

Chain catches on the sliding lift mechanism as the door goes up or down. Unable to adjust out the problem with adjustment nut. May have to try removing chain links to fix the droop of the long chain.

Allowed me to install for a 9 foot garage door. Worked well to extend a 7 foot garage door opener. Comes with the extension and new chain. Directions are kind of cryptic, but there are plenty of videos on YouTube. Would buy from HD again.
