Ensign Boom Cap, gooseneck end
Cast aluminum boom fitting, gooseneck end. Check the height of your boom cross section to confirm which end you need to order. Many earlier boats have the 3 1/2 inch boom, which is a different extrusion than the mast. Later boats have the 4 inch boom, which is the same extrusion as the mast. Use with the Ensign Spars Gooseneck.
The boom caps will occasionally require light grinding to fit your boom section.
