Bench-Mount Roller Chain Breakers
Push both chain pins out of your roller chain with the pull of a handle. These chain breakers make it easy to disassemble your chain to add or remove links. Since they mount to a work surface, they give you extra leverage and are convenient for frequent jobs.
Pair chain breakers with a die (sold separately) that matches your roller chain trade size. Dies have two pockets that cup the bottom of a chain to quickly align it with these breakers.
