Product Description
The JoPo Grips Pitch Gauge – Large (1‑1/16" to 1‑7/16") is designed to deliver exact pitch measurements for oversized thumb holes and interchangeable thumb systems. Covering diameters from 1‑1/16" through 1‑7/16", this gauge is ideal for measuring outer sleeves and large thumb holes used in modern systems like JoPo Twist, VISE IT and Turbo Switch Grip, helping drillers achieve the ideal fit for each bowler’s hand.
Constructed from durable steel, the JoPo large pitch gauge features a machined measurement face that reads pitch without guesswork, providing repeatable forward, reverse and lateral pitch readings across multiple balls. Its easy‑to‑read design and clearly marked indicators allow pro shop technicians to quickly drop the gauge into the thumb hole, align it with the ball’s reference axes, and see the exact pitch value, reducing trial‑and‑error and improving consistency.
Engineered for optimal performance and equipment care, the JoPo large pitch gauge helps drillers ensure that interchangeable thumb outer sleeves and large thumb holes match the bowler’s specs, maximizing grip, control and confidence on the lanes. Used together with the JoPo medium pitch gauge for smaller thumb sizes, it forms a complete pitch‑measurement system that covers nearly all common thumb diameters.
JoPo Pitch Gauge Large 1 1/16" to 1 7/16" FAQ
What thumb hole sizes does the JoPo Large Pitch Gauge cover?
The JoPo Grips Large Pitch Gauge is designed for thumb holes ranging from 1‑1/16" to 1‑7/16", covering oversized conventional thumbs and most interchangeable thumb outer sleeves used in systems like JoPo Twist, VISE IT and Turbo Switch Grip.
How does the large gauge help with interchangeable thumbs?
By measuring the pitch of the actual outer sleeve or large thumb hole, the gauge ensures that interchangeable thumbs installed in those sleeves share the same underlying pitch, improving fit consistency when swapping thumbs across balls.
What is the construction of the JoPo Large Pitch Gauge?
The gauge features steel construction with a machined measurement face, providing durability and highly repeatable pitch reads for daily pro shop use.
Is the JoPo Large Pitch Gauge easy to read?
Yes. The gauge is designed with clearly marked pitch indicators and an easy‑to‑read layout, allowing drillers to quickly see and record forward, reverse, and lateral pitch values.
Can the JoPo Large Pitch Gauge be used with standard thumb holes?
It is optimized for larger thumb diameters (1‑1/16" to 1‑7/16"). For smaller, more standard thumb sizes, JoPo’s Medium Pitch Gauge (11/16" to 1‑1/16") is recommended to maintain accurate centering and measurement.
How does the large gauge fit into a complete pitch‑measurement system?
JoPo offers both medium and large pitch gauges, and a combo with a holder, covering the full range of thumb hole sizes. Using the appropriate gauge for each hole diameter ensures precise pitch measurements across a bowler’s entire arsenal.
