Crosby® McKissick 12" Sheave Block w/ Shackle & Roller Bearings: 3/4" wire

Regular price $2,28200

Description

This 12" Crosby® McKissick sheave block is a 419 type snatch block sized for 3/4" wire rope, built with a forged steel swivel shackle and roller bearings for smoother rotation under repeated cycling. The shackle assembly interchanges across the 4-1/2" to 14" McKissick size range, letting crews standardize rigging sheave hardware. It's engineered to meet or exceed ASME B30.26 requirements.

Key Features

  • 12" sheave sized to run 3/4" wire rope
  • Forged steel swivel shackle in place of a hook end
  • Roller bearings for smoother rotation under frequent-cycle use
  • Shackle assembly interchanges across the 4-1/2" to 14" McKissick size range
  • Engineered to meet or exceed ASME B30.26 requirements

Applications

  • Rolling block rigging setups calling for a shackle end rather than a hook
  • Crane and hoist work running 3/4" wire rope
  • Frequent-cycle jobs where roller bearings reduce wear over time
  • Rigging sheave needs where a Crosby sheave block with a shackle fits better than a hook
