...specifically, the one made by Ninka and sold by B&Q:
short version
Has anyone here ever installed one? I confess to being baffled by the single diagrammatic sheet of assembly instructions, and to judge by some of the comments on the B&Q site I'm not alone.
Most of the procedure is pretty obvious, but the assembly at the base of the column, the "brake/cam" has me defeated, at least temporarily. I simply can't fathom how it should be orientated relative to the front of the cabinet, and how it's supposed to function.
Many thanks.
