This Heavy-Duty Binding Post is a high-performance electrical terminal designed for secure power distribution and premium audio signal transmission. With an overall length of 34.65mm and a robust 14.75mm base diameter, these connectors are engineered to provide stable, low-resistance connections for amplifiers, test equipment, and industrial control panels.
Versatile 4-Way Connection: Engineered to accommodate multiple termination styles, including standard 4mm banana plugs through the top jack, bare wire via the side-entry cross-hole, and ring or spade terminals under the screw head.
Industrial Color Coding: Available in high-visibility Red (Positive) and Black (Negative) to ensure immediate polarity identification and prevent accidental short circuits.
Precision-Machined Threaded Shaft: Features a smooth-acting threaded post that allows for high manual torque, ensuring a gas-tight electrical contact even in high-vibration environments.
Integrated Solder-Lug Interface: Includes an angled metal solder tab at the base, facilitating permanent and reliable internal wiring within your device chassis.
Secure Panel Mounting: Equipped with a heavy-duty hexagonal nut and threaded chassis for stable installation through standardized circular panel cutouts.
Reinforced Ribbed Grip: The high-impact thermoplastic caps feature vertical ribbing to provide a non-slip surface for easy hand-tightening without the need for specialized tools.
Dimensions: 34.65mm (Total Length) x 14.75mm (Base Diameter).
Interface: 4mm Standard Banana Jack.
Material: Nickel-Plated Conductive Core with ABS Insulation.
Mounting Type: Threaded Nut Panel Mount.
Termination: Solder Tab / Threaded Stud.
Application: Ideal for laboratory power supplies, high-fidelity speaker cabinets, custom amplifier builds, and industrial testing jigs.
What makes this better than the smaller 28mm versions? The extra length (34.65mm) and wider base (14.75mm) provide significantly more surface area for wire contact and allow the post to be mounted through much thicker panel materials, such as heavy-duty wooden speaker baffles or thick-walled industrial enclosures.
Can I use this for high-wattage home theater speakers? Absolutely. The solid metal core and secure clamping mechanism are designed to handle high-current signals without overheating or degrading audio quality, making them perfect for premium audio applications.
Will the connection loosen over time? When properly tightened using the dual-nut system (internal locking nut and external clamping cap), these terminals provide a vibration-resistant connection that remains secure even during transport or high-decibel playback.
