RECOIL 3/8-inch Feed-Thru Battery Terminal Connector — 450A Brass Stud, Watertight Panel Mount

The RECOIL BTTP-38 is a heavy-duty 3/8” feed-thru panel battery terminal designed to route high-current cables through bulkheads, decks, or firewalls while preventing chafe and providing secure electrical access rated up to 450 amps.

Engineered for marine, automotive, RV, and industrial installations, the BTTP-38 simplifies bringing large power leads from one compartment to another without sacrificing protection or reliability. Instead of forcing bulky cables through a basic grommet, this feed-thru replaces the vulnerable wire pass-through with a robust brass stud, sealed mounting face, and durable hardware so you get tidy, serviceable connections and improved strain relief.

How does the BTTP-38 make routing heavy cables safer?

The unit replaces a plain hole or rubber grommet with a threaded brass stud and body that carries the conductor through the panel. That prevents the cable jacket from rubbing against sharp edges and concentrates mechanical load on the terminal assembly rather than the wire.

• 3/8” heavy-duty brass stud minimizes cable wear and resists corrosion
• Flanged mounting face can be sealed with gasket or bedding compound for watertight installations
• Nylon lock nuts and stainless steel screws maintain clamping force in harsh environments
• Included silicone terminal caps protect exposed posts from shorts and salt spray

What electrical capacity and materials should I expect?

Built for demanding power distribution, the BTTP-38 uses a substantial brass stud and body that provide low resistance and long-term conductivity. The connector is rated for high-current use up to 450 amps when properly installed, making it suitable for battery feeds and large accessory circuits.

• Rated for 450 amps on the 3/8” brass stud
• Brass conductors for excellent electrical performance
• Nylon hardware and silicone covers for insulation and environmental protection
• Stainless steel fasteners resist corrosion in marine or outdoor settings

How do I install the BTTP-38 for a watertight, vibration-resistant fit?

Installation is straightforward: cut the correct-sized hole, apply a gasket or bedding compound to the mounting face, insert the feed-thru, and secure with the supplied lock nuts and screws. Tightening the fasteners compresses the seal and locks the assembly against rotation so cables remain strain-relieved even under vibration.

• Drill a clean, properly sized 3/8” pass-through opening as instructed
• Apply gasket or marine bedding compound to the flange for a water-resistant seal
• Use the supplied stainless screws and nylon lock nuts to secure the unit
• Cover exposed studs with included silicone terminal covers for safety

Who is this for? The RECOIL BTTP-38 is aimed at installers and DIYers who need a rugged way to route high-current battery or accessory cables through panels without chafing, moisture ingress, or loose connections. It's especially useful in boats, off-road vehicles, RVs, toolboxes, and any application where large-gauge leads must pass through bulkheads or decks and remain serviceable. Choose this feed-thru when you want a professional, long-lasting solution that combines high amp capacity with corrosion-resistant materials and simple installation.
