Laboratory and field tested.
After a 2000 hour weatherometer test, per ASTM G53, an independent laboratory reported that "... samples remain unchanged from unexposed material. All of the exposed specimens remained flexible and showed no signs of cracking."
The revolutionary RhinoTube dock fenders have been through extensive lab and field tests for over five years and in various conditions. After these years of testing, RhinoTube dock fenders have remained durable and flexible, showing no signs of cracking.
The UV-protected colors of the dock fenders have proven to not fade, wash off, or mark up your watercraft. The overall integrity and design of RhinoTube dock fenders has proven to provide effective and reliable protection.
