RECOIL Feed-Thru Battery Terminal Connector 3/8" Brass Stud — 450A Watertight Marine/Auto

RECOIL BTTP-38 is a heavy-duty 3/8” feed-thru panel battery terminal connector engineered to pass high-current cables safely through firewalls, bulkheads, decks, or panels while providing strain relief and a watertight mount.

The RECOIL BTTP-38 simplifies routing large power cables where space and abrasion are concerns. Instead of forcing a grommeted cable through a hole and risking chafing or poor strain relief, this feed-thru replaces the cable end with a secure brass terminal stud that carries up to 450 amps. Built for marine, automotive, and industrial panels, the assembly includes corrosion-resistant fasteners and protective silicone covers for a tidy, durable installation.

How does the BTTP-38 prevent cable chafing and improve strain relief?

The feed-thru eliminates direct cable entry into panel openings by using a heavy brass stud as the electrical pass-through. That means the cable is terminated to a lug or ring that fastens to the stud, preventing repeated flexing and abrasion at the hole edge. The result is longer cable life and a more secure electrical connection.

• 3/8” brass stud accepts ring or lug terminations for secure clamping.
• Terminal mount isolates cable movement from the panel opening.
• Includes silicone covers to protect the exposed terminal and insulation.
• Durable nylon lock nuts and stainless screws maintain clamping force in vibration.

Is the RECOIL BTTP-38 suitable for marine and outdoor installations?

Yes. The design anticipates wet and corrosive environments: stainless fasteners resist rust and the mounting face can be gasketed or bedded to produce a watertight seal. This lets you install the connector in boat hulls, decks, or exterior panels where splash or spray is possible without compromising the electrical feed.

• Gasketable mounting face for a sealed installation.
• Stainless screws and nylon lock nuts minimize corrosion and loosening.
• Silicone terminal covers shield the exposed stud from moisture and salt spray.
• Suitable for bulkheads and enclosures where water-tightness is required.

What electrical capacity and hardware features does this feed-thru offer?

The BTTP-38 uses a heavy-duty 3/8” brass stud rated to 450 amps, making it appropriate for high-current accessories and battery distribution points. The rugged materials and locking hardware ensure a reliable mechanical and electrical connection under load and vibration. It is sized to accept large ring terminals so you can connect battery cables without downsizing conductors.

• 3/8” brass stud rated for up to 450 Amps continuous duty.
• Designed to accept heavy-gauge ring or lug terminals for large cables.
• Nylon lock nuts preserve torque and resist loosening under vibration.
• Comes with silicone covers for professional, safe termination protection.

How do I install the BTTP-38 in a panel or hull?

Installation is straightforward: drill the specified 3/8” feed hole plus mounting holes if required, fit the feed-thru through the panel, and secure with the supplied stainless screws and nylon nuts. Use sealant or a gasket on the mounting face for a watertight finish, then connect your ring terminal to the brass stud and fit the silicone cover.

• Drill appropriate hole and position the feed-thru on the panel surface.
• Use sealant or gasket around the mounting face for a waterproof seal.
• Tighten nylon lock nuts and stainless screws to specified torque to prevent loosening.
• Attach ring terminal to the 3/8” stud and slide on silicone cover for protection.

Who is this for: The RECOIL BTTP-38 is aimed at boat owners, automotive electricians, off-grid installers, and equipment fabricators who need a robust, high-current pass-through that prevents cable wear and ensures a durable, clean connection. If you routinely route large battery cables through panels or require a sealed, professional-looking feed point for inverters, battery banks, or accessory distribution, this terminal feed-thru provides a reliable, serviceable solution.
