The Wooden Camera Adapter for Dual Director’s Monitor Cage v3 works in combination with two Director’s Monitor Cage v3 kits to let you create a dual-monitor setup. When the cages are placed side by side, just attach these adapters to the 15mm rods on the top and bottom to connect the cages. Each adapter has a thumbscrew to secure it to the rods. Please note, this rental is for the adapter set only. If you also need to rent compatible monitor cages, Wooden Camera Director’s Monitor Cage v3 with Gold Mount or V-Mount battery compatibility are available as separate rental items.
