The DDC-55 makes it possible to block the position of the device on rails or quick-release plates that comply with the Arca-Swiss standard.

Thanks to the perpendicular fastening system, it is possible to work in two axes and to obtain a straight angle between attached rails or quick-release plates, thanks to which the position of the device can be moved on two planes.

The scale applied on the handle allows you to move the inserted rail by hand, and the spirit level helps you to set the camera precisely.

Robust knobs ensure fast and efficient tightening and unscrewing, and the fastening mechanism itself runs smoothly and perfectly holds the rails or quick-release plates included in it.

The set is made of aluminum, making it durable and lightweight.

The box contains:

• DDC-55 double holder
• 1/4″-3/8″ reduction
• Reduction key
