The RECK FH45S was designed to house the Mini Innofader Plus and a 24mm arcade button on the Numark PT01 Scratch. The 24mm arcade button can be used for a start/stop mod, or anything creative you can think of. It’s designed to be mounted at 45° while allowing the case to be closed. It uses both the original hardware from the PT01 Scratch and the included hardware from the Mini Innofader plus to mount. To reduce the stem height so that you can use it with the cover, use the 4mm standoffs that are included with your Mini Innofader plus. It can be use with or without the standoffs. But the lid will only close with the standoffs installed. Take into consideration the wiring of the Mini Innofader Plus and carefully tuck it to avoid pinching.
