The SYS-AZ is part of your custom build storage solution. This solution could be fixed in place or on wheels. The SYS-AZ is an individual drawer and slide mechanism. When a Systainer is on the SYS-AZ and pulled out, the Systainer lid can be fully opened.
Each SYS-AZ can carry up to 44 lbs. Your box construction should be 16-13/16" (427mm) wide by 14-31/32" (380 mm) or more deep, with a minimum of 1/2" (13mm) under the bottom drawer and 5/16" (8mm) above the top drawer.
