The 2" nosepiece for the ARCO 2" rotator (PrimaLuceLab, SKU: PL3600413 ) converts the telescopic side of the ARCO 2" rotator into a classic 2" insert sleeve (Ø 50.8 mm). This allows the rotator to be easily attached to any pulley or adapter with a 2" clamp without additional adapters.

Key Features

• conversion: ARCO 2" flange → 2" insert sleeve (Ø 50.8 mm)
• full internal diameter 50.9 mm – no vignetting for APS-C sensors
• short optical length (approx. 15 mm) – minimal impact on the back-focus budget
• milled 6061-T6 aluminum, hard anodized – lightweight and corrosion resistant
• blackened, grooved interior - reduced reflections, better contrast
• two M4 threads – possibility of additional securing of the nose with locking screws (screws included)
