Assembly instructions.

The ASSWH1 Steering Wheel Holder locks a vehicle’s steering wheel in place, so the front wheels stay still during alignment, mechanical repairs, or long-term storage. In a shop or a home garage, it helps prevent unintended wheel movement, for a safer working environment and more consistent readings.

!Important safety note

  • Do not disassemble this device. Internal components are factory-calibrated, and tampering may compromise safety and function.
