Has anyone fitted framed kitchen units please. Expletives coming from DH - it is just not obvious how to fit the frame - instructions/pre-drilled holes look they are for a frameless model, but supplier ensures us that all cabinets are the same for framed or unframed. There are no pre-drilled holes to attach the frames. Are we missing something. Anyone out there experienced the same, or got a kitchen fitter handy they can ask. Thanks.
