I used this VEVOR unit \"off-color\", to create additional storage space in my INDOOR DuraSteel 18 in x 30 in SS kitchen work mini island. Kitchen is tight, so I needed an extra work surface and more storage. With the purchase of an extra DuraSteel shelf I was able to stably support/wedge in the VEVOR unit. No hardware required. The unit specs are 17.8\" W x 20.2\" H x 12.2\" D. It still left me the bottom (original) shelf, for more storage. BTW, the extra shelf runs only $33/from \"returns\". The VEVOR unit does leave some back shelf space unused - it is 12.7 in to the units' 18 in depth. Not a big deal. You will notice that I placed the VEVOR unit off center. That is because I plan to \"close off\" the end gap in some manner to slot in a wooden chopping block. BTW, I feel that the 18 in x 30 in DuraSteel top dimensions are an absolute minimum for a functional area to perform most kitchen tasks. Also, wheels are a must in a small kitchen. The unit is topped off with a Winco CBWT-1830 Cutting Board, 18-Inch by 30-Inch by 1/2-Inch. It fits great but slides on top of the SS top surface. My solution: DIYMAG Neodymium \"finger\" magnets as seen in the pics (left). These are super strong yet can be removed. They do stick to this SS surface to contain movement of the board.
