The ARS-1 Cube Set from ARRI combines the Accessory Rail ARS-1 and the Accessory Rail Cube ARC-1. It is a simple, quick and reliable way to attach and detach accessories. The Accessory Rail Cube ARC-1 can be used on the SMB and LMB Accessory Adapter as well as on the Accessory Rails ARC-1, ARC-2 and ARC-3. It can be locked off by turning the lever 90°. Accessories such as an articulating arm or a Cinetape can be mounted on four integrated 3/8-16”, which offers eight different holes for securing pins. The Accessory Rail Small ARS-1 shares the same rail interface as the SMB and the LMB Accessory Adapter. Two ball-pressure pieces on each side of the rail prevent an attached Accessory Rail Bracket ARB-1 from slipping off. It is compatible with all 3/8-16” interfaces which offer holes for the two securing pins. Uniquely, four different sizes of hex key can be used with the Accessory Rail Small without having to adjust it - 3,4, 5 and 5/32” will all fit perfectly.
