Yes! Just YES! My husband is in residential construction and I often end up doing a lot of the finish work and custom builds when it comes to cabinetry. Getting cabinet doors right has always been easiest/fastest with an extra set of hands until I got jig. It's lightweight but very sturdy and stable and allows me to hang cabinet doors FASTER than working with an extra pair of hands. Takes guess work out, keeps things level and steady. Ridiculously easy to use.
This product only works with frameless cabinets, but it has been such a time saver for me, I have purchased similar jigs for framed cabinets and other setups.
HIGHLY recommend. My husband has even started hanging cabinet doors himself because it takes a lot of the frustration out of the process and makes it less time-consuming.
