This replaces the clamp on you Manfrotto RC4 style QR and replaces it with an offset Arca style adapter. Note that you have to remove the Manfrotto clamp to attach this one.
This unit is intended for the 410 head and is 4.5" long. On the 410, the clamp will be centered over the vertical axis of the tripod. It will work with other heads but the axis may not be centered.
It is a very well made unit.
It is is very lightly worn and works perfectly. The clamp is smooth and locks tightly.
