Crosby HR-1000 UNC Threads – Bolt Size 1-1/4 - 7 x 5.00

Product Description

Product Description:
Crosby HR-1000 UNC Thread Swivel Hoist Rings are designed for heavy-duty lifting applications, providing a strong, adjustable lifting point that allows loads to rotate and align naturally during lifting.
These hoist rings feature a 360° swivel and 180° pivot, ensuring proper load alignment and significantly reducing side loading compared to traditional eye bolts. They are ideal for industrial lifting, fabrication, and machinery handling where flexibility and strength are critical.
