The Leofoto 12mm Screw Knob Clamp is an Arca Swiss clamp with a 1/4" thread enabling you to clamp onto for example an Arca Swiss compatible lens support rail or L-Plate. This allows you to easily attach an accessory with a ‚¼-inch screw hole to your L-bracket.
The Leofoto 12mm Screw Knob Clamp also has a ‚¼-inch screw hole where you can place, for example, a Magic Arm, giving you even more possibilities to combine accessories. With the grey dial, you can set the distance between the Arca Swiss clamp hooks. The clamp plate is 12mm wide. By using CNC aircraft aluminium, the DC-12 clamp weighs only 18 grams.
