Review: Lo compre para abrir mi portón crrediso que mide 2.80 más y alcanzo muy bien
Review: Had to get this extension for our garage door opener because we have an 8' door. Frustrating that there isn't an option to just buy the full garage door opening system for an 8' door in the first place. The extension works, but annoying to have to pay extra money. The product itself, works well.

## Questions & Answers

**Q: does this work on the B750 model Chamberlain?**
A: Yes, this would be the appropriate rail extension kit for your Chamberlain B750 opener.

**Q: Will this fit the chamberlain whisperer model 248739 ?**
A: According to Chamberlain's web site, yes.  Search for "chamberlain "248739"", you should find a downloadable parts manual; "8808CB 8 Foot (2.4 m) Rail extension kit" is listed for Models WD822KD • WD832KD • 248739, page 37.

**Q: I have a 12 x 16 foot door. Do I need to purchase an extension kit? If so, which one?**
A: You will definitely need an extension kit.  The opener is designed for a standard 7ft. door and therefore the rail (and belt on it) is only long enough to raise a door 7ft.  I have an 8ft door and only bought the extension for the additional 1 ft.  You should probably contact Chamberlain to see if they offer an extension for a 12ft door.  It might require a different type of opener.

**Q: Do I need to purchase the extension kit for the garage door opener to work?**
A: You have to purchase extension if door is 8 foot tall or it will not work.
