The Aero Lite and Aero ice screw caps were designed with the intent to not only protect the ice screw teeth, but to also solve several problems:
The loop on the caps allows for a quick, one-handed operation when removing the screw and allows the cap to easily be racked on the users'ice clipper. Another feature on the ice screw cap are the vents. We put vents on the sides and bottom of the caps to allow airflow for any left-over ice/water to drain and allow the screw tip to dry.
Only compatible with BLUE ICE AERO and AERO LITE screws.
