The Klarity O-type / U-frame Demi-Baseplate is specifically designed for the Elekta HexaPOD ™ evo RT System, but is equally useful for situations requiring a shortened baseplate. The O-type / U-frame Demi-Baseplate works with all O-type 3-point and 5-point masks, as well as all U-frame masks. The lower portion gently tapers for patient comfort and the carbon fiber construction makes for an extremely lightweight board.
