This Crosby® McKissick 18" sheave block is a 419 type snatch block with a forged steel swivel shackle and roller bearings, sized for 1" wire rope. It's one of the larger sizes in the McKissick line, built for heavier rigging loads where a bigger sheave diameter is needed. The shackle assembly interchanges across the 4-1/2" to 14" McKissick size range, and the block meets or exceeds ASME B30.26 requirements.

Key Features

• 18" sheave sized for 1" wire rope
