Square Accessory Sleeve SAS-1 The Square Accessory Sleeve SAS-1 is required to mount the Viewfinder Mounting Bracket VMB-5 to your camera and has been designed with a rectangular rod to prevent the viewfinder falling when loosening the adjustment clamp. The SAS-1 has been designed with the CCH-5 top handle in mind but can be mounted to any two M4 attachment points spaced 20 mm apart, as regularly found on ARRI camera accessories.
