Everything you could possibly want in one quick-release plate. PROplate works in ARCA-type tripod heads, and can also be configured to fit in both ARCA and most Manfrotto® RC2 tripod heads (see the full list of compatible tripods here). Slides into Capture in 4 directions. Contains 4 loops for Peak Design Anchors. Machined/anodized aluminum construction. Note that this item is a newer version of the DUALplate (sold out) and ARCAplate, which can be purchased for $19.95 each while supplies last.
