Overview of Series 75 Orbit Block, Single, 3" Sheave Size, 5,400lb. SWL, 12oz..

The 75mm webbing block (RF79107) can be used where swivel head and shackle attachment is not required to achieve further weight savings.

Bearings: High-compression–strength Carbon Black Acetal; Torlon needle rollers
Sheave Size: 2-3/8" (60mm) or 3" (75mm)
Line Diameter: Series 60: 1/2" (12mm), Series 75: 9/16" (14mm)
