RECOIL 3/8in Feed-Thru Panel Terminal — 450A Brass Stud, Marine-Grade Strain Relief and Corrosion Resistance

The RECOIL BTTP-38 is a heavy-duty 3/8" feed‑thru panel terminal that safely routes and secures high‑current cables through firewalls, decks, hulls or bulkheads.

Built for marine, automotive, and industrial installations where large battery or accessory cables must pass through a barrier, the BTTP-38 replaces exposed cable holes with a dedicated, strain‑relieving terminal. Its 3/8" brass stud provides a secure electrical connection rated to 450 amps while the included fasteners and silicone covers help create a durable, serviceable penetration point.

How does the BTTP-38 prevent cable chafing and stress at panel openings?

The feed‑thru isolates the cable from sharp edges and distributes mechanical load to the terminal body instead of the cable jacket. That prevents abrasion at the hole and reduces the chance of loosening from vibration or movement.

• Closed brass bushing protects cable insulation where it passes through panel openings.
• Built‑in strain relief transfers pull forces to the terminal assembly rather than the conductor.
• Nylon lock nuts and stainless steel screws hold the unit tightly in place under vibration.
• Recoil silicone terminal covers guard posts from accidental shorts and corrosion.

Is the BTTP-38 suitable for waterproof or weather‑exposed installations?

The terminal’s mounting face is designed to accept gaskets or bedding compounds to achieve a watertight seal when installed correctly. This makes it suitable for wet environments like boat decks, engine compartments, and exterior panels when coupled with proper sealing materials.

• Mounting face can be gasketed or bedded to prevent water ingress.
• Stainless screws resist corrosion in marine conditions.
• Nylon hardware resists deterioration and helps maintain a tight seal.
• Silicone covers add an extra barrier against moisture and salt spray.

What electrical capacity and hardware does the BTTP-38 offer?

The BTTP-38 uses a heavy‑duty 3/8" brass stud engineered to handle high‑current loads up to 450 amps, making it appropriate for large alternators, battery banks, winches, inverters and other demanding accessories. The package includes corrosion‑resistant mounting hardware and protective covers to deliver a reliable connection.

• 3/8" brass stud rated at 450 Amps for high‑current applications.
• Durable nylon lock nuts to resist loosening under vibration.
• Stainless steel screws for secure, corrosion‑resistant mounting.
• Recoil silicone terminal covers included for safe, neat installations.

How easy is the BTTP-38 to fit into existing panels or bulkheads?

Installation requires a 3/8" compatible hole and basic hand tools; the unit mounts from the outside and tightens with the supplied hardware. Because the mounting face accepts gasket or bedding material, installers can customize sealing and finish to match the vehicle or vessel.

• Simple panel cut‑out and through‑bolt mounting with supplied screws and nuts.
• Accepts common bedding compounds or gaskets for tailored sealing.
• Compact profile keeps access areas neat and organized.
• Includes silicone covers for immediate post‑install protection.

Who is this for: The RECOIL BTTP-38 is aimed at boat builders, vehicle upfitters, electricians and DIY enthusiasts who need a rugged, high‑amp pass‑through for battery cables and power accessories. If you require a secure, vibration‑resistant feed‑through that can be sealed against moisture and rated for heavy current, this terminal delivers the mechanical strength and electrical capacity expected in professional installations.
