The RPS-180 attaches to the frontplate of the RPS column and enables levelling of the camera in 3 directions.

It features an (ARCA compatible) dove tail and comes with a 1/4" quick release plate. Dove tail equipped cameras,  such as the Cambo ACTUS-Repro or WRC-400 Repro attach directly to the RPS-180 without the need for a QR plate.
