Ikea method Kitchencabinet lifting tool

I am building a new kitchen with some large cabinets. (2 meters)at the end after closing up the back you need to lift the cabinet but you can put presure sideways on the feet. (they will break)My wife isnt strong enough so i created this little tool.Slide it at the bottem side facing down. (use some small cloth to prevent damage)and you can lift up the cabinet.Smaller version is 47mm. (i reduced the feet to 50mm in total to fit it in my kitchen)the bigger version is 79mm (the normal feet is 80mm.) no second person needed this way. and less risk to damage the cabinets.the slit is 22mm. thickness of the wood part is 20mm. 2 mm room for some cloth to prevent damage.Added photo's of the real thing.Works great. No damage to the cabinet. and easy to lift on your own
