Stemball / Eye Adapters


Masthead Stemball / Eye Adapters
Stemball / Eye Adapters are used on Mastheads made by Isomat, FranceSpar, Sparcraft and other Spar builders for attachment of the Headstay and Backstay. All Stemball / Eye Adapters incorporate a Cup Washer. Used with a Toggle, they offer superior articulation and more connection options than standard Stemballs. They should always be used on a Headstay and are required for use with all furling systems. Used on the Backstay, in addition to improved toggling action, they simplify installation of Insulators. Available with Toggle or separately. See, for example, Isomat NG1 and NG2 Mastheads.
For other Masthead attachments, See: Masthead and Forestay Toggles.
