For 15mm support you slide the SC 15mm Interface Bridge Plate in the SC Bottom Interface Plate. SC 15mm Interface Bridge Plate – OCTAMAS gear

We splitted the LW 15mm support from the SC Bottom Interface Plate to make the SWISS cage as universal and camera independent as possible. 

You can use the SC 15mm Interface Bridge Plate with the other SC Bottom Interface Plate for ARRI, Canon too. And if a new RED camera is coming out you only need to buy a new SC Bottom Interface Plate as you still can use all other parts of the SWISS cage.

You attach to the SC 15mm Interface Bridge Plate the SC Dovetail Plate 140 SC Dovetail Plate 140 – OCTAMAS gear

This way you can attach the camera to a quick release tripod plate or any 19mm or 15mm Studio Bridge Plate.

The SC 15mm Interface Bridge Plate also provides a ARRI standard dovetail mount. 

Our SWISS cage supports correct LW 15mm, 15mm Studio and 19mm heights on Top and Bottom.
