Egis Feed Through Terminal, Red M8 (5/16") Bulkhead Pass-Through
Egis Feed Through Terminal, Red M8 (5/16") Bulkhead Pass-Through — Product description
Need to run high-current DC power through a bulkhead, deck, or transom without hacking up the panel? The Egis feed-through terminal gives you a clean, insulated pass-through on a red-coded M8 (5/16") stud. Stainless self-locking hardware holds tight, and glass-filled composite insulators keep everything isolated where the cable crosses the wall.
If you've ever tried to get a heavy battery cable from one side of a bulkhead to the other, you know the drill. Drill an oversized hole, seal around the cable, hope it holds. The Egis feed-through terminal does it properly. It's a studded pass-through that carries high-current DC power through bulkhead walls, decks, and transoms while keeping the conductor insulated from the surrounding structure.
The stud is an M8, which is the 5/16" size most marine lugs are cut for, so your existing ring terminals bolt right on. Egis builds these with insert-molded conductors and glass-filled composite insulators, so the current path stays isolated and the terminal holds up to the damp, salty air down in a bilge or a rigging tunnel. The stainless steel hardware is self-locking, which means it won't back off with engine vibration and pounding seas.
This one's red, so it's the natural pick for your positive run. It ships as a single terminal in a retail pack. Running both legs through the same bulkhead? You'll want a second terminal for the negative side too.

Frequently asked questions
What does a feed-through terminal do?
It passes high-current DC power from one side of a bulkhead, deck, or transom to the other through a single insulated stud. Instead of running a bare cable through an oversized hole, you land a ring terminal on each side of the stud, and the conductor stays isolated from the surrounding structure.
What size stud is this?
It's an M8 stud, which is the same as 5/16". Most marine battery and accessory ring terminals are cut for 5/16", so they thread right on without an adapter.
Why is it red?
Egis color-codes these terminals so you can keep polarity straight. Red is the conventional choice for your positive power run. If you're feeding both legs through the same wall, use a second terminal for the negative side.
Will it hold up in a wet, vibrating install?
That's what it's built for. The conductors are insert-molded and the insulators are glass-filled composite, so the terminal shrugs off the damp, salty conditions in a bilge or rigging tunnel. The self-locking stainless hardware won't vibrate loose.
