Manfrotto XPRO3-Way Head MHXPRO-3W SUNWAYFOTO DLC-60LX Both knobs and levers allow for quick and secure attachment to plates from multiple manufacturers. The levers have a locking function to prevent accidental opening and are made of CNC-machined, aircraft-grade anodized aluminum. Since I mainly use a geared head, this item is in excellent condition, having been used only a few times. The plate is missing, so it is not included. Please purchase separately. Thank you for looking.
