Rail for storing Stanley organizer boxes. It locks them in place so the don't fall out with a small lip in the front. They sit flush with the front of the cabinet, so you dont bump into them.
The rails are split for easier print of small printers.
The rails fit cabinets with an inside measurement of 425-430mm. They are made to fit Festool cabinets for SYS AZ drawers, with an internal width of 427mm. The two larger holes fit with the SYS AZ hole spacing of 58mm from the front and the next hole at 224mm from the front.
There are also screw holes from the back, these are in case you need extra reinforcement for very heavy boxes.
Printet laying flat on the backside.
