Question: is only one hinge per door required ?
Document: These are great hinges, the soft close is in the hinge so no piggyback soft close to get in the way of what you wan't to put in the cabinet. I bought one pair here to check them out and then in bulk at local wholesale supplier.
These hinges feel sturdy upon installation but were a little tricky to install and adjust. and i wish they weren't so bulky
The stripped screws are a huge disappoint for me because I am not a professional and for cabinet hanging, being off by even 1-2 mm looks weird. Currently my cabinet doors are slightly off and I have to decide whether to live with it or drill new holes since I can't make the easy adjustments.
I ordered these hinges from Amazon because every other vendor sold the parts separately and no other vendor clearly explained which parts go with the others. Amazon's genius idea to sell the set saved me a lot of stress.I used these to hang custom cabinet doors in a powder room cabinet.I am giving these 3 stars instead of 5 because each 3-way adjustment screw was stripped. Not slightly stripped, but completely unusable.
I am very happy with these. I used them for frameless inset installation. Instructions were adequate.Since this was my first installation of cabinet doors, and I had some errors, the 3-way adjustment proved to be priceless!
Answer: no
