Selden 45mm Auto Ratchet Block
Selden ratchet blocks are designed for applications like dinghy main sheets and spinnaker sheets. The block makes it easy to advance your grip when hauling in the sheet and creates the perfect combination of control and convenience.
The sheave automatically changes from free-turning to ratchet when the load increases, with fully adjustable ratchet engagement to a higher or lower load to suit your personal sailing style. A special insert locates the shackle at 0 degrees, 90 degrees, or free swiveling.
