Is the USBC Banning the Purple Hammer Urethane Bowling Ball?
USBC Updates National Tournament Rules in Relation to Purple Hammer Bowling Ball
ARLINGTON, Texas – The United States Bowling Congress is aware of a claim that a portion of the Purple Hammer bowling balls manufactured at the Ebonite International plant in 2016 and 2017 may have been produced below USBC’s minimum 72D hardness specification. The Hammer brand was purchased by Brunswick Bowling Products in 2019, and the Ebonite plant subsequently closed.
USBC conducted an investigation, interviewing more than a dozen individuals, including former Ebonite employees, in an attempt to validate the claim. Brunswick fully cooperated with the investigation.
USBC has confirmed a production change with the Purple Hammer took place in 2017 that resulted in the raising of the hardness of the ball from its original 2016 approval level just over 72D to about 74D. This production change was fully compliant with USBC equipment specification requirements.
During USBC’s investigation, multiple former Ebonite employees, including ones with first-hand knowledge, told USBC they believe the production process in 2016 and 2017, prior to the production change, led to some Purple Hammers being unintentionally produced below 72D. No one interviewed by USBC provided evidence Purple Hammers were produced under 72D. No one interviewed by USBC provided evidence Ebonite knowingly distributed balls outside of specification.
The findings of USBC’s investigation are inconclusive. However, the credible first-hand accounts describing the potential for an unknown number of Purple Hammer balls to be produced out of specification in 2016 and 2017 is concerning.
Therefore, effective immediately, USBC is instituting a tournament rule at all USBC national tournaments prohibiting Purple Hammers manufactured in 2016 and 2017 from being used in these competitions. The tournament rule reads:
Purple Hammer bowling balls manufactured during 2016 or 2017 (identified by serial numbers that start with either a “6” or “7”) are prohibited for use.
USBC has shared this national tournament rule with Hammer’s current owner, Brunswick, and has Brunswick’s support. Brunswick will offer owners of 2016 or 2017 Purple Hammers the option to exchange their balls for a new Purple Hammer that can be used in all tournaments or a product of their choice. This can be done on-site at the 2022 USBC Open Championships or USBC Women’s Championships, or by contacting Brunswick at: [email protected] or 800-937-2695.
The Purple Hammer, including the 2016 and 2017 models, remain USBC approved. USBC’s equipment specification manual allows for revocation of ball approval when balls at the time of manufacture demonstrate non-compliance to specification. USBC has no such evidence and is unable to locate enough blank balls from 2016 and 2017 to conduct conclusive testing.
Each USBC competition, whether tournament or league, has the option to adopt USBC’s national tournament rule on the Purple Hammer or other rules related to equipment restrictions.

Bowlers should ban USBC…
With absolutely no evidence, not one single example, they ban the balls from national competition. I thought this was America.
