Rocksolid guarantee

Shop with confidence. If it’s not working out, you can return it (consumables, electronics, undergarments and swimwear excluded).
Really. If it's not up to snuff after you use it (a couple times) you can still bring it back. It lasts longer than 30 days, but not forever. We'll be fair about it.


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
