The rail does not have a pre-cut thread for bolting the rail´s side - the included 5mm screw is self-cutting so when you mount the rails to side panels, a thread will be cut into the rail automatically. You don´t need further tools like thread-cutters!
You can NOT bolt the modules directly to the rail - you need either gliding nuts or threaded strips first which you have to insert into the rails first. Suitable threaded strips are available here with order number PM138049. Included in delivery is the rail and two M5x20 screws with a flat hexagonal socket head.
You need two rails for one row of modules!
The rails are 17.05 inch (43.3 cm) long. Therefore, they can be easily joined with rack ears and mounted in a 19” rack.
attention: the 19" rails are compatible with Doepfer's G6 cases and inherent to the design ca. 6mm longer than these which are supplied in Doepfer's DIY kit!
If the DIY kit is to be expanded by more rows, the 19" rails offered here have to be shortened to a lenght of 427mm (= 84HP)!
