Designed for garage door installation professionals, the Raynor Garage Door Engineering Assistant makes complex calculations simple, even at the job site. Based on Raynor’s popular desktop application, the android version includes calculators for common installation planning and setup requirements:

• Torsion spring selection & setup
• Extension spring selection & setup
• Extension spring load
• Spring conversions
• Installer turns and drum information
• Drum comparisons
• Operator door speed

The app is preloaded with data for different drum models and springs made by Raynor as well as other manufacturers. By entering known information such as door width, height, weight, track length and other factors, you can quickly design a spring, calculate replacement springs, calculate installer turns, design an extension spring or determine spring loads for existing extension springs, plus other common tasks.
