M42/M48/M54 CAA 360 Degree Rotator Adjuster Modular Three-in-one

M42, M48, and M54 CAA 360 Degree Rotator Adjuster Modular Three-in-one is a precision aluminum alloy adjuster for astronomy accessories. It features modular screw structures with M42, M48, and M54 thread sizes, enabling flexible configuration. The rotating mechanism uses stainless steel swing screws and silicone damping rings to ensure smooth, oil-free operation. Designed for secure mounting and stable alignment, it supports high-precision positioning in telescope systems.

  • Modular design allows mixing M42/M48/M54 screw structures for custom configurations
  • Stainless steel swing screws provide strength and durability with a smooth, precise rotation
  • Silicone damping rings eliminate oil leakage risks and reduce vibration during adjustment
  • Anti-slip teeth and red-black color scheme improve grip and visual clarity during use
  • 12.5 mm thickness extension ensures consistent spacing across all models
  • Five stainless steel screws with included wrench enable secure, tool-based assembly
