In making frames for SYS-AZ, the instructions say to drill the front row of holes 58 mm from the front of the cabinet, and the back row 224 mm behind that. The LR 32 set up guide doesn't reach that far back. (I'm doing these as back to back cabinets, so I cannot measure from the back, which would include extra steps and chances for error anyway.) Why isn't there a long bar for the LR 32 setup guide that reaches to the back row of cabinet pins?
