The Leofoto LH-55NN No Neck Low Profile Ball Head is a 55mm ball head for target shooting and support weight up to 55lbs. Crafted from aircraft-grade aluminum and hard anodized, the LH-55NN has all of the qualities you would expect from a professional-level head. It has an oversized and ergonomic locking knob. And a separate tension knob is provided to apply the appropriate pressure that safely corresponds to the weight of your equipment. A third knob loosens and locks the panning base which is laser-engraved with markers every 2.5 degrees from 0 to 360 degrees. The Leofoto LH-55NN has all the same great features found on the LH ball head series, but further decreases the height creating an extremely low profile setup.
