Manfrotto Leveling Center Column 055PRO with 50mm Leveling Ball

The 555B replaces the center column of an 055PRO with one that carries a 50 mm leveling half ball at the top, so the head levels without time-consuming adjustment to the length and angle of every leg.

The ball locks and unlocks from a turning grip at the bottom of the column, and that grip can be removed while the column is being fitted. The top plate has a male 3/8 in screw for a photo or video head plus a bubble spirit level. Aluminum, 41.7 cm (16.42 in) long, 0.67 kg (1.48 lb), rated to 7 kg (15.43 lb).
