We have kitchen cupboard doors set in frames which are hinged with the concealed hinges (26mm/110 degrees I think) that are commonly found. However because the doors are set in frames the part of the hinge which is mounted on the inside of the unit has a metal spacer attached to it to bring the hinge out level with the edge of the frame.
Unfortunately one of the hinges has snapped but I have found it impossible so far to source a replacement hinge with spacer - all DIY shops and websites I have visited just have the standard hinges for a flush fitting door with no frame.
Any ideas where I could find a replacement?! The kitchen was installed by the previous owners of the house so I have no idea where it came from otherwise I could go back to the manufacturers. There must be a number of kitchen manufacturers making framed door units so I should have thought that there would be some demand for this sort of replacement hinge.
