Amplifier TERMINAL Heavy (Red/Black) (Banana plug Binding post) Code: 93273818

A 4mm banana plug speaker terminal (or binding post) lets you quickly plug in your speaker wires instead of wrapping bare copper. It consists of a metal cylinder with an exact 4mm hole. They use a side-spring mechanism to grip the socket tightly. This gives you clean, noise-free, and secure audio.

Here are the key details:

• Size:The plug pin is exactly 4 mm (about of an inch) wide.
• Wire Size:These terminals accept standard speaker wires (usually up to 4 mm² or 11 AWG).
• Colors:They come in red and black pairs. Red is positive (+), and black is negative (-). This helps you            match the left and right speakers correctly.
• How to Connect:Just strip the plastic off the end of your speaker wire, insert the wire into the banana plug, and tighten the screw. You do not need to solder anything. Then, simply push the plug straight into the terminal hole.

• Compatibility:Most standard audio receivers and bookshelf speakers use this 4 mm size.
