When I read your question I thought..."Well maybe I can help with this one.." My GC just finished putting my soft close hinges on my Kraftmaid cabs yesterday. There were a couple leftovers, so I ran downstairs and am looking at the bag... I ordered these with my Kraftmaid cabinets from Home Depot The bag says... Blumotion For Doors blum Polybag kit fo compact hinges 971A9700.22 2.624.664.3 Asembled in the USA Components Made In Austria The back of the bag gives directions for Full overlay and Partial overlay application. I hope that helps you out!

I installed these on all my kitchen cabinet doors after a facelift remodel: https://www.rokhardware.com/hardware-fasteners/soft-close-add-ons/blumotion-soft-close-with-spacer-screws-polybag.html I think I got mine from Rockler for about $3 each, but a lot of places sell them. I installed them all using a Dremel stylus. My cabs are full overlay. No problems. It's been 5 years and nary a slam. I wasn't sure if I'd need the adapter piece, so I ordered one. Ended up not needing the adapter so saved some money getting devices without. Laurie, my doors are painted maple shaker with MDF inserts. They are not super heavy. The door doesn't just up and close on its own. You give it a bit of a shove, as you would with a door that doesn't soft close, and momentum does the rest.

On the new Blum hinges there is a deactivation switch, looks like a little grey pyramid on the actual hinge cup. Slide it.

This is why I never hire contractors. I much prefer to work directly with the people doing the work. The people I finally dealt with on my custom cabinets were great - small shop in an industrial area. The guy who sold me the package also builds the cabinets with one or two other guys. One of the guys who builds the cabinets and paints them was the installer (one man installation). Always try to deal directly with the person who is going to do the actual work - you end up with better product and spend less money to boot. I'd make the contractor or cabinet maker or whoever you signed the deal with on the cabinets replace all the hinges with current technology BLUM soft close hinges - ALL of them. Or find a supplier for the BLUM hinges (Richelieu sells them here in Canada) and withhold that much from your final payment to them, plus $40 per door minimum for labor fees to replace them all. Play hardball - it's your money, it's your house, it's your deal. Hold them to every letter of the deal you signed - don't pay a penny more, and hold back on whatever they skimped on.
