Our Marine Electrical Line
The Captain's Locker® electrical range is built around one principle: connections that hold, in conditions that will test them. Engine rooms run hot. Bilges collect moisture. Salt air attacks bare copper within a season. Every product in this lineup is chosen specifically because it handles all three.
The line covers the connections that matter most on any vessel — from fine-gauge instrument wiring to the heavy cables that run between your batteries, alternator, and starting circuit:
-
Waterproof Heat Shrink Connectors — HDPE polyolefin butt connectors, ring terminals, and tab/push-on terminals with a dual-wall adhesive liner that bonds to the wire jacket on heat application, creating a fully sealed, corrosion-proof splice. Available in 22–18 AWG through 12–10 AWG. 30-piece packs keep the parts locker stocked.
-
Heavy-Duty Marine Battery Lugs — Tinned copper cable lugs for 1/0, 2/0, 4/0 gauge wire in 5/16", 3/8", and 1/2" stud sizes. Built for starter circuits, inverter hookups, windlass feeds, and any high-current application where a loose or corroded connection is a serious problem.
-
Adhesive-Lined Heat Shrink Tubing — 3:1 shrink ratio tubing with internal adhesive for fully sealed wire protection on terminals, cable ends, and repair splices. Available in multiple sizes and lengths.
All Captain's Locker® electrical products ship from Long Beach, CA — in stock and ready to go.
