Tenth Frame Finger Thumb Dams Oval 120 Count

Thumb fit decides the release before the ball ever leaves your hand.

A hole that drifts a hair wide changes every shot. Dams close the gap.

Performance Under Pressure: Loose thumbs cause early release and inconsistent rev. The ball exits different every frame and the pocket moves. Dammed holes give the same release shot after shot.
Durability: Closed cell foam holds shape under sweat and pressure. No compression over a long block, no mid-match slip.
Friction Removal: Sized oval to match the hole shape. No edge catching, no hesitation on the exit. The ball leaves clean every time.
Identity Signal: 120 count is pro shop supply. Bowlers who keep a bag of dams are bowlers who know fit changes everything.
Proof and Credibility: Built for pro shop use. The standard for professional ball drilling and fit correction.

Dial the fit. Repeat the release. Let the score take care of itself.
