Show Description

Expanding spring-loaded tube chocks with lock-off screw collar is effective in offwidth cracks. Depress the button to allow the tube to expand to the width of a crack and then tighten the collar to lock the unit into place. Big Bros are relatively light, compact, and stable compared to spring-loaded camming devices.

  • Offset ends allow for secure angled placement.
  • Holes at one end of the tube need to be slung.
  • Made of aluminum.
