Abstract
A chock wherein a movable inner member is received for relative vertical movement in a housing with the inner member having a conventional diagonal slot therein for receiving a line. The housing has a central counter bore at the top thereof, and a smaller bore extending therefrom and said inner member is received in the housing for relative axial movement between a depressed inoperative position and an upper operative position. A set screw carried by the housing engages a slot in the inner member for limiting relative axial movement therebetween, while a spring loaded poppet carried by the housing is engageable with a detent near the bottom of the inner member to resiliently hold the inner member vertically stationary relative to the housing when in its upper position.
