Extension chain - Too short
On adding the 8’ extension kit to my new Chamberlain ½ HP opener, I found the extension chain too short and was unable to continue assembly. With the extra 1 foot extension rail, the chain supplied was only 22 inches. It needs to be at least 24 inches. Doh!

      The extension worked fine, but I made a mistake in buying it. I have a 7 ft door, should have measured it with a tape instead of a yard stick. The big problem is the range of the controller, I need to be almost in the garage to make it work.
