Dana Dolly 6" Riser

The Dana Dolly 6" Mitchell Riser Plate is suitable for use on
your dolly or jib with a standard Mitchell mount and provides a fixed 6"
rise. It is made from CNC machined 6061 aluminum and hard anodized
black for wear and corrosion resistance. It supports up to 100 pounds
and the base features a removable guide bolt.

The riser can be useful for dolly shots in parallel with the rails to help keep them out of frame, as well for "underslinging" the camera beneath the dolly.
