Description
Get an accurate, repeatable pitch reading without the wobble common to single-point gauges. The RDTL Pitch Gauge uses a self-centering rack-and-pinion mechanism so both calipers extend symmetrically and reference the bore wall at two points — giving you a true center reading every time, whether you’re fitting a customer or dialing in your own grip.
Features:
- Self-Centering Mechanism: A rack-and-pinion drive keeps both calipers moving in sync.
- Two-Edge Bore Reference: Measures against two points along the bore wall for the most accurate pitch angle measurement.
- Direct-Read Fan Scale: Graduated scale calculated from true geometry, not approximated — read the angle directly, no math required.
- Two-Gauge Set: Two gauge sizes to cover 1/2″ to 1-1/2″, nesting into a custom-fit storage base.
Built for pro shop technicians and serious bowlers who want a pitch reading they can trust — not just a number.
