Snatch blocks are a very versatile rigging tool as they are used for hoisting and re-directing loads. The name snatch refers to the ability of the block to quickly and easily insert the rope or cable into the sheave groove. In many block or pulley designs, the end of the cable must be passed through the block or pulley. With snatch blocks, a component of the block is able to swing or pivot out of the way to enable the cable to be inserted onto the sheave. This feature makes the snatch block a very useful fitting in the field.
Snatch blocks have an ultimate strength 4 times the working load limit. As with all block and pulley applications, one must pay close attention to working angles.
