Ratchet Blocks

Ratchet Blocks by Harken and Ronstan

Ratchet Blocks

Ratchet blocks are commonly used for main sheets and other high load applications where holding power is necessary for proper sail control. Depending on size, most ratchet blocks have an on/off function or are load sensing, automatically locking under high load to help control the line.
