The Ripley Cablematic CB-6667-H is the factory replacement cutting blade for the full JST Series of coaxial cable jacket stripping tools. It is designed to restore a worn or damaged JST tool to like-new cutting performance, making it an essential consumable for cable technicians and linemen working with trunk and distribution coaxial infrastructure.

This blade is confirmed compatible with the JST-500, JST-565, JST-625, JST-700, JST-750, JST-840, and JST-875 jacket strippers — covering the entire JST color-coded family from 500 kcmil through 875 kcmil cable sizes. The JST tools themselves are engineered to strip oversized and flooded cable jackets from cables including CommScope P3, Times Fiber T4 Plus, T6, and T10, and the CB-6667-H blade is factory-set to minimize scoring or nicking of the aluminum sheath beneath the jacket.

Note: The CB-6667-H (with the -H suffix) is the JST jacket stripper blade and is a distinct part from the CB-6667 (no suffix), which is a separate replacement blade for Ripley's WS49 end stripper and square-cut 4x4 bushings. Confirm the -H suffix when ordering to ensure the correct blade for your JST tool.
