Product Description
Not every polyester ball is created equal. The Hammer Black Widow Spare+ pairs the iconic Gas Mask core with a polyester cover to create a uniquely versatile spare ball. It delivers the accuracy bowlers demand for spare shooting while offering enough core dynamics to become a valuable option on extremely dry lanes and shorter patterns with less oil volume. Whether it's used for converting corner pins or navigating the toughest lane conditions, the Black Widow Spare+ is ready for the challenge. Wrapped in a striking White Diamond pearl finish with eye-catching sparkle, it's every bit as bold as the Black Widow name deserves, finished at 500, 1000, and 2000 Siaair / Factory Polish and rated for a straight reaction on light oil. It's available in 10–16 pound weights and backed by a one-year warranty.
