Manfrotto 577 Rapid Connect Adapter
Theft not covered.
The Manfrotto 577 Rapid Connect Adapter gives you the freedom to remove the camera from the head without detaching it from the plate to quickly put on another support item.
Notes: The plate for this adapter offers both a 1/4"-20 and 3/8"-16 camera attachment. Loss of these screws may result in a fee. It is compatible with the Manfrotto 501HDV, 503, and 519 heads, including the Manfrotto Fluid Head Video Monopod.
