Just cutout templates are based on the overall size of your undermount sink. For example, Just sink model number US-1620-A, or US-ADA-1620-B would use a template US1620. To easily find the cut-out template for your sink, hit CTRL F and enter the size of your sink (e.g.; 1620, 1830).
Please note: each DXF file is packaged its own zip file.
