This Crosby® McKissick 418 type single sheave block features an 18" sheave built to run 1" wire rope, pairing a forged alloy, heat treated hook with roller bearings for low-drag rotation. The hook assembly interchanges across the 4-1/2" to 14" McKissick size range, letting crews standardize hardware across a mixed rigging inventory. It's engineered to meet or exceed ASME B30.26 requirements.

Key Features

• 18" sheave sized to run 1" wire rope
• Forged alloy, heat treated hook built for strength and wear resistance
• Roller bearings for smoother sheave rotation under frequent cycling
• Hook assembly interchanges across the 4-1/2" to 14" McKissick size range
• Engineered to meet or exceed ASME B30.26 requirements

Applications

• Crane and hoist rigging calling for a single sheave block with hook
• Heavy wire rope redirection and load positioning on the job site
• High-cycle lifting work where roller bearings outlast plain bushings
• Rigging inventories standardizing on interchangeable McKissick hook hardware
