The LHC-60 60mm Screw-Knob Clamp from Leofoto is an Arca-type receiver clamp, with 60mm long jaws, made to convert existing ball heads to Arca-type quick release systems. It may also be used as a replacement part or when customizing shooting rigs. It features an integrated bubble level plus laser-engraved scale markings for precision placement of compatible quick release plates. The clamp jaws open and close by twisting the large, ergonomic knurled knob.

The LHC-60 60mm 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.Leofoto LHC-60 60mm Screw-Knob Clamp With Plate:
