The bridge plate BP-13 is equivalent to the BP-12, but for 15 mm studio
rods.
Note: Make sure bridge plates are tightened firmly with a screwdriver, not the
commonly used coin!

The bridge plate adapter BPA-1 can be used to attach a BP-3/BP-5/BP-
8/BP-9 to ALEXA. First attach the BPA-1 to the camera with the two
screws. Then attach the bridge plate to the adaptor with its two screws.
Make sure the screws are tightened firmly with a screwdriver.
