Review on Upgrade Your Cabinet Game With Neitra'S Heavy Duty Door Mounting Jig And Clamp - Perfect For Face Frame And Frameless Cabinets! by Brian Rogers

This tool makes it easier to mount cabinet doors by acting as a 3rd hand that holds the door at the desired height so that hinges can be attached. It will make it a little easier to install upper cabinet doors, but it won't work on lower cabinet doors with less than 3.5" between floor and bottom of cabinet. So, it does work, but it has very limited use. I would not recommend this jig to anyone needing to install multiple or upper and lower cabinets.
