Rolling Down The Lane™ Precision Hand Span Measuring Tool (with Interchangeable Inserts) – Pro Grade

Description

Engineered for absolute accuracy, the Rolling Down The Lane Span Measuring Tool takes the guesswork out of bowling ball layouts. Whether you are outfitting a full-service Pro Shop or drilling your own arsenal at home, consistent fit is everything.

Unlike standard metal rulers that can slip or be difficult to read on a curved surface, our span tool is designed to contour naturally to the ball.  No complex setup or internal moving parts that can fail. This complete kit includes precision-fit inserts, allowing you to accurately measure cut-to-cut distances and copy existing grips with zero slop. Field-tested in active pro shops to ensure professional-grade reliability.

• Industrial-Grade Material: Manufactured from rigid, high-strength filament (ASA for the span tool and PLA+ for the inserts and base holder) to completely eliminate tool flex and ensure absolute dimensional accuracy, reading after reading.

• Complete Insert System: Includes precision-fit, interchangeable inserts that lock securely into existing holes to map cut-to-cut distances with zero slop.
