The Shark™ Collapsible Step Chock will save critical storage space on your rig for more important life saving equipment. Its innovative design is taller than most traditional step chocks, collapses to 5½" and is designed to nest together when stored for further space savings. You can fit 4 Sharks™ in less space than 2 wood or plastic chocks require.

The Sharks™ tough steel construction meets the 2:1 height to base ratio requirement while positive grip teeth on the steps bite into anything they come in contact with. The Sharks™ base-plate accepts ratchet straps or pickets to prevent slipping in icy or muddy rescue conditions.
