Roller-Chain Puller

A jaw-type Roller-Chain Puller allows one to add or remove individual links. Its jaws (about 2 inches apart when opened) are slipped into the links on both sides of the problem area; then its knob- or T-shaped handle is rotated to draw the jaws together, which pulls and holds the links close enough to add/remove.

Cost: $15-$330, depending on chain size and handle type
