"As other have commented, the instructions are poor but, as I was moving cabinets which already had some parts fixed, I was easily able to see how they worked. Measuring needs to be reasonably precise, but any fine adjustments can be made using the mechanism on the fixings. The final result is very strong and I wouldn't hesitate to use the fixings again. The fixings are still the same as those used on the old kitchen units 17 years earlier so the design appears to have stood the test of time."
"Instructions are OK, but don't mention you need to have ~20mm recess for these hangers to sit flush with the wall. I moved the back in my kitchen cupboard to make the recess large enough.
Adjustments are basic (especially vertical), but work fine.
Someone buying 'concealed' hinges probably needs them hidden as the back face of their kitchen cupboard is on show. Why they choose to supply grey plastic covers I'm not sure, white would blend better! Had some white covers left over from kitchen refit (see photo)."
"Essentially a very strong fixing, if you can be sure of using it correctly, and if you can find it in the Screwfix catalogue - it is concealed in the Kitchen sections - one of Screwfix's best kept secrets.
Solid metal casting with vertical and horizontal adjustments. Adjustable bracket fixes to rear of cabinet. Smaller bracket fixes to wall. I guess that the idea is to hang the larger bracket onto the smaller one, but this is not stated or shown in the drawing.
The instruction leaflet lets down the product. There is insufficient detail to show how to use this fixing. Consequently, rather than let down a customer and my reputation, I resorted to a long wooden batten and exchanged these fixings for another requirement."
