Why "snatch" blocks?
The snatch block is one of today's most widely used types of blocks. As generally applied, its title refers to that group of intermittent-service blocks which quickly attaches and "snatches" or moves loads over comparatively short distances. This as opposed to long lifts and continuous service for which crane and construction blocks are designed.










Overhaul Balls and Pins.
Ball and pin assemblies are obtainable as replacement parts for Johnson Blocks overhaul balls or as add-on/conversion kits for Johnson Blocks swivels. Ranging in weight from 37 to 1,161 pounds, these units consist of cast iron ball, steel pin, and the necessary nuts and cotters.
