Harken Unit 3 MKIV Furling System Toggles
Harken toggle assemblies accept standard turnbuckles with swage, rod, Norseman, or Sta-Lok terminals. Unit 3 toggles are available in three styles and multiple pin sizes for 3/4", 7/8", 1" and 1-1/8" headstay/chainplate clevis pins. This is a required purchase for all Unit 3 MKIV Ocean furlers and also a required purchase for those Unit 3 MKIV Racing furlers sold without an included toggle.
A single stainless steel clevis pin provides access to the turnbuckle for adjustment. The #7413.20 and #7513.20 Heavy Duty (Short Link Plate) Jaw x Jaw Toggles include reinforcing side plates which attach to the four threaded sockets in the bottom of the furler's lower unit. They do not raise the drum or change the length of the furler assembly.
