About Chris
The Surewinder garage door torsion spring winding wrench is patent pending and has been successfully used in the field for over 5 years. The Surewinder wrench can prevent repetitive motion injuries such as shoulder rotator cuff tears ( see www.dasma.com/articles/feature/Injuries_Sum2017.pd… ). The prevention of just 2 days of lost work due to strain, sprains, or other injury pays for the wrench.
See Surewinder.com for more information.
