Abstract
A snatch block which may be opened to receive a line has a sheave assembly and a pair of sideplates on the sides of the sheave assembly, as well as a head connecting the sideplates. One of the sideplates and sheave is hinged from the head and can pivot toward and away from the other sideplate. A spring loaded plunger is carried by the sheave and engages an aperture in the other sideplate to lock the assembly. The plunger is pushed by a lever in the other direction to open the block.
