The U-75-090-0170 is an aviation-grade wheel chock set (pair) used to prevent aircraft movement on the ground during parking, maintenance, or loading operations. It is designed specifically for light aircraft ground handling, ensuring secure wheel immobilization even on slightly uneven surfaces.

These chocks are placed in front of and behind aircraft wheels (typically main landing gear) to provide physical restraint in addition to parking brakes, reducing the risk of unintended rolling due to slope, wind, or brake failure.

Key features include:
