ARRI Rosettes & Pins vs. Manfrotto RC2
Comparing 2 standards across 11 specifications. 11 key differences identified.
The ARRI Rosette (31.8 mm diameter with 60 radial teeth and an M6 central thread) and ARRI 3/8"-16 Anti-Twist Locating Pins (dual 3.0 mm indexing holes flanking a 3/8"-16 screw) are the de facto cinema rigging standards developed by Arnold & Richter Cine Technik (ARRI) to prevent camera cage accessories from twisting under heavy rotational torque.
The Manfrotto RC2 System (utilizing the 200PL rectangular quick-release plate) is the dominant consumer and prosumer quick-release standard in photo/video heads (Manfrotto 496, 498, Befree, 322RC2). Featuring a drop-in tapered aluminum wedge plate with an automatic spring-loaded locking cam and secondary brass safety catch.
