The DDC-60L Screw-Knob Dovetail Clamp from Sunwayfoto is an Arca-type compatible clamp that features an extended locking knob and a removable bubble level. There is a numbered scale on both sides of the clamp to help balance your camera with easy repeatability. The clamp is CNC machined from aluminum and has a satin anodized finish to provide abrasion and corrosion resistance. A 3/8"-16 to 1/4"-20 bushing reducer and an Allen wrench are included with the clamp.

The extended knob prevents cameras or wide plates from covering it, making locking and unlocking the clamp easier.

Safety-stop grooves allow you to adjust the plate's location without the plate accidentally being released.
