Hammer Black Widow Spare+

The Hammer Black Widow Spare+ combines a polyester coverstock with the Black Widow line’s distinctive core design. Built primarily for accurate spare shooting, it also gives bowlers an option for extremely dry lanes and shorter patterns with less oil.

A 500, 1000, 2000 Siaair and Factory Polish finish helps the ball travel straight through light oil. The White Diamond colorway adds pearl sparkle with a bold Black Widow logo. Core designs vary by weight: the heavier versions use the Gas Mask design, while 10-11 lb models have a low differential and no published asymmetry value.

• Polyester cover for spare shooting and light-oil conditions
