The black Manfrotto 055XCCSB Short Center Column is an optional short column for 055X, 055CX and other select X series tripods. It's also compatible with 3011N, 3021N, 3221WN and 3021PRO series tripods. Although most of these tripods already include the low angle adapter built into the standard center column - with loss of up/down control - the 055XCCSB still retains vertical movement control. This shorter column is ideal for situations where the legs are set at the third angle of inclination (about 60°), but still require the possibility to move the camera up and down to achieve perfect adjustment for the shot. This shorter column replaces the one supplied with the tripod.
