E-Section Internal Gooseneck Assemblies

E-Section Outhaul Assemblies

E-Section Standard Boom Accessories
 


E-Section Internal Gooseneck Assemblies
Kenyon Internal Gooseneck Assemblies allow easy control of up to three internal lines. An outhaul on the bottom centerline which is led to a cleat on the underside of the boom, and one or two reef lines which can be cleated with integral friction-lock lever-action cams, or led to the deck and cleated aft.
Note: Kenyon Internal Gooseneck Assemblies are now equipped with the new friction-lock lever-action cams for greater holding ability, and SS cover plates to keep the reef lines captive at all times. Old-Style units featured Spring Cams (with or w/o handles), and different reef sheaves than the improved version. The Old-Style units are easily identified by the absence of the SS cover plates. While upgrading to the improved style using one of the K-11443 Conversion Kits (below) is recommended, original parts for the Old-Style gooseneck are still available. See Parts for Old-Style E-Section Internal Gooseneck.
