A ZUD 1/4" 20 is used to retrofit your existing articulating arm, giving you Zacuto Z-Release (quick release) action on one or both ends of the articulating arm. ZUDs are now all black. ZUDs convert your 1/4" 20 or 3/8" 16 screws to 15mm rods, thus allowing them to fit into Zacuto Z-Release components like Z-mounts, 15mm Z-locks, ZicroMounts and all other Zacuto 15mm locking devices.

An additional feature of a ZUD; any Zacuto male rod can screw into the end of the ZUD allowing you to create an extension to your articulating arm. The articulating arm is not included.
