Description du produit
The Crosby HG-226 Eye & Eye Turnbuckle is engineered for heavy-duty rigging and tensioning applications requiring dependable load adjustment, superior fatigue resistance, and secure attachment points. Designed for straight or in-line pull applications only, these heavy-duty turnbuckles provide reliable tension control for industrial rigging, construction projects, marine environments, utility systems, and overhead lifting operations.
Manufactured from quenched and tempered or normalized steel with hot-dip galvanized protection, the HG-226 turnbuckles deliver exceptional durability and dependable long-term performance in demanding outdoor and industrial conditions. Forged elongated eye ends minimize stress concentration while allowing easier attachment in rigging systems, making these turnbuckles ideal for repeated heavy-duty tensioning applications.
