The Manfrotto 324 5/8" Survey Adapter and Plate is made of two pieces: a 5/8" bushing with a 3/8" female attachment to connect it to a tripod, and a removable plate, 4.9" in diameter with a 5/8" male thread, that should stay connected to the equipment.
With this adapter, it is possible to transform any Manfrotto tripod into a tripod compatible with the standard attachment interface system used in the survey and measuring industry.
