I own both RED and GDU side handles as well as RED Komodo Outrigger handle but I don’t believe that can be used with your cage.

Do your RED, GDU handles have a rosette to mount on camera? If yes, you can attach any Rosette to 3/8” Adapter to mount on our Top and Bottom Interface Plates.

If I remember rightly I read on Reduser that the Komodo Outrigger handle fits the V-RAPTOR. If that’s the case you can mount it on the camera and can at  the same time mount our Top Interface Plate.
