Jayhawk Span Rule II
The Jayhawk Span Rule II is a professional measuring and marking tool designed for bowling ball drilling and layout work. Its flexible steel construction allows accurate span measurements and makes it easy to draw reference lines and markings directly on the bowling ball surface.
Unlike a rigid ruler, the flexible Span Rule II follows the curved surface of a bowling ball, allowing measurements and markings to be made with greater control and convenience.
The tool is particularly useful when preparing bowling ball drilling layouts and transferring previously determined grip measurements. Its clearly readable scale assists with measuring spans and positioning finger and thumb holes.
With a length of 8 inches, the Span Rule II is compact and versatile. Its durable steel construction makes it a practical measuring tool for everyday professional ProShop use.
