The Arca-Swiss Type Leofoto LHC-50 50mm Screw-Knob Pro Clamp is designed to transfer existing ballheads to Arca-Type quick release systems, or it can be used as a replacement part. For precision placement the Leofoto LHC-50 50mm Screw-Knob Pro Clamp features a bubble level and laser-engraved scale markings.
The LHC-50 50mm clamp incorporates a 3/8″-16 threaded mounting socket and an 18 x 22mm plus-shaped, 5mm-wide mounting groove to prevent it from rotating when mounted on compatible ball head stems.
