The Campbell T7550421 is a compact yet powerful 1-1/2-inch double sheave pulley designed for fixed-position installations where dual-line routing is required. Featuring a rigid eye connection, this pulley is ideal for static applications such as barn door systems, garage hoists, trailer rigs, and utility setups where directional control and load distribution are critical.

Built with a steel body and die-cast zinc sheaves, the T7550421 offers long-lasting durability and corrosion resistance. Its zinc-plated finish protects against rust in both indoor and outdoor environments, while the powder metal bushings ensure smooth sheave rotation under load. The double sheave design allows for independent or coordinated use of two ropes, enhancing versatility in lifting and guiding systems.

Key Features:

• Double Sheave Configuration
  Supports two ropes for dual-line lifting, guiding, or tensioning applications.

• Rigid Eye Mount
  Fixed eye provides a stable, non-swiveling anchor point for secure installations.

• Heavy-Duty Steel Body
  Engineered for strength and reliability in demanding environments.

• Die-Cast Zinc Sheaves
  Durable and corrosion-resistant, designed for smooth rope movement.

• Zinc-Plated Finish
