The sheave is the part of the block that comes into direct contact with the conductor. Its material is critical for protecting the conductor and ensuring a smooth pull.

• Aluminum Alloy Sheaves: Known for their lightweight design and high strength, these are the industry standard. We offer them with a neoprene lining to provide extra protection against damage and surface abrasion on the conductor.

• High-Strength Nylon Sheaves: A popular choice for their superior properties in preventing damage to the conductor's surface and reducing friction. They are also non-conductive, which adds a layer of safety during installation.

• Steel Sheaves: While durable, they are generally used in the central part of multi-sheave blocks or in applications where the conductor's surface is not as sensitive.
