I know there are already a couple of threads re: the Lee Valley unit, but I wanted to share a couple of pics of my newly installed unit. I installed it in an already installed 49" blind corner cabinet, countertops and everything already there. It is possible, and actually pretty easy to fit it in. I can see it being quite a bit more difficult in a smaller cabinet though
Here's the cabinet with door/drawer removed

Here's the hard bracket to install. this installs to the "back" of the cabinet, but the rub is that the "back" is hardboard, not wood and doesn't provide much support. It also screws in from the sides into the side of the cabinet, but in the 49" blind corner cab, the bracket doesn't reach the deep end.

My solution was to cut and install a 2x2 vertically to provide a screw support for the hanging back end. I measured the width of the bracket and installed the 2x2 so that it fit nice and snug

I skipped photos for a couple of steps (got excited things were moving along), but here is the extension bracket installed. Next to installing the back bracket, getting the sliding bracket "just right" was a bit touchy. Just go slow and figure out how it all goes together, and it just magically works

all in all, took about an hour to install it. I had to fiddle with the door mounting a bit to get it "just right" and might need a bit more tweaking. But overall I'm very impressed with this hardware and would definately recommend it to anyone.
The install sheet is a bit thin, and the measurements are all in mm, but for the most part you can just install as you go. The only critical measurements are the door mounting, and of course the overall dimensions for installation.
Cheers!
