Tenth Frame Finger Thumb Dams Round 120 Count

The release you trust starts with a hole that holds.

Round holes drift wide as the hand swells. Dams close the gap and keep the fit honest.

Performance Under Pressure: Sweat and heat expand the hand through a long block. The thumb hole grows loose and the ball exits unpredictable. Dammed holes repeat the release under pressure.
Durability: Closed cell foam resists compression and moisture. The dam sits where it was set, no creep, no mid-squad slip.
Friction Removal: Round profile matches the drilled hole without catching on the exit. The ball leaves clean, the rev comes off the fingers the same way every shot.
Identity Signal: 120 count is pro shop stock. Bowlers who keep a bag of dams are dialed in about fit.
Proof and Credibility: The working standard for fit correction in professional ball drilling.

Keep the fit locked. Keep the release the same. Bowl the score you are capable of.
