The CRITR3 is a canyoneering rappel device that lets you easily add friction WHILE RAPPELLING. The CRITR2’s unique design minimizes rope twists on single line rappels and also locks off easily. The CRITR3 is symmetrical and can be flipped over for extended wear in sandy conditions. The CRITR3 is now optimized to run smoother on larger diameter ropes with lighter people. This innovative rappel device, originally made by Canyon Werks, is now an Imlay Canyon Gear product.
