Hi Silviu,

The QuickDesign Pro libraries already include the Tandem box sliders:

The hardware can be applied using the appropriate manufacturing method :

You can download the Pro libraries from the Premium Support area here:

If you need any hardware that’s not in the libraries you can use the free hardware setup service.

To use this service please post the exact details of the drilling patterns required and we will set the hardware up in a cabinet so that you can restore it to complete your libraries.

The drilling details can be posted as a drawing or the manufacturer’s technical document, but please be as specific as possible.

Best regards,

Ness
