Fiddle ratchet block with swivel / becket for sailboats (max. line ø : 12 mm)
055 Harken

Low-friction Fiddle blocks build three- and four-part purchases. They come in a variety of configurations, including Fiddles with Cam-Matic cleats on adjustable arms and Fiddles with on/off Hexaratchet® switches that toggle the ratchet mechanism. Fast trim and release under high or low loads.
Ratchets grip loaded sheets, yet allow line to be eased with complete control. They feature Hardkoteanodized, Teflon®-impregnated eight-sided sheaves machined from solid aluminum for strength and corrosion resistance. Delrin® ball bearings, sheave, and sideplates are UV stabilized with carbon black for maximum protection. High-strength stainless steel straps reinforce blocks.
For easy removal, add a 111 snap shackle to the Little Fiddle and a 112 to the Fiddle.
