I went to Burbank IKEA this morning and bought my first cabinet.The IKEA kitchen lady looked at my design and pointed out that I do not have enough clearance for fridge. Back to design again... But I bought one wall cabinet I know for sure won't change.
I took home a 30" X 39" frame, 2 Karsebo Beech doors, one long hanging rail, and 2 bags of hinges. I now know why hundreds of packages arepossible if one orders a whole kitchen. With my simple order like this, they still missed one item. After I pointed out and waited for another 20 minutes, I went home happy.
Athome Ibegan assembling the 30" X 39" birch frame. I accidentally chippedthe sidea little. Wife is not happy, but she got over it since we will have a side panel for Karsebo Beech later.
I have few screws left. Thereare twopair of srews (two male,two female) which I do not know what function they serve.
I borrowed the two pictures below; one from Susan, and one from Bret's website to showwhat are in Bret's picture, but not in Susan's.
I know Bret used 2 1/2" deck screws to put up the hanging rail, so I need to do to HomeDepot for those. I know the ones from Susan's picture are to hang the cabinets. But I do not know whatthe extra srews showing in Bret's picture are used for.
Please advise.
