W-500 is an Overhead Garage Door Torsion Spring Tensioning Tool for commercial and industrial sectional doors with springs ranging from 3.75" to 6". It can accommodate both 1.0 and 1.25 diameter shafts. This device prevents work-related accidents and significantly reduces physical strain during the torsion spring cranking process
The SW-500 is designed for use with a cordless drill (Non-impact) with a 13mm socket to make the job faster and safer than using winding bars.
***Richard Wilcox springs require the SW-500-ADAPTER.
