When identifying a marine ring terminal, the hole in the ring is just as important as the wire size it accepts. Ancor makes heat-shrink terminals for specific AWG ranges and mounting studs, with multiple packages for some otherwise matching sizes. Compare the original connection with the exact part-number chart before ordering.
Identify the ring and crimp barrel
The crimp barrel must suit the conductor. The three groups here are 22–18, 16–14 and 12–10 AWG.
Identify whether the connection uses a #8, #10, 5/16-inch or 3/8-inch fastening stud.
Some sizes are sold in different pack counts; do not mistake a different quantity for a different fitting size.

What to check before a replacement crimp
Record the original cable's AWG, the stud diameter and any corrosion or overheating around the terminal. A ring hole that is too large or too small for its intended fastener can compromise the connection. Use a suitable marine crimp tool and follow the terminal manufacturer's instructions.
A 16–14 AWG ring terminal with a 3/8-inch hole does not fit the same fastener as a 16–14 AWG terminal with a #8 or #10 hole. Both specifications must match the actual installation.
