CM20B Stackable Banana Plug | 4mm | Black

This 4mm stackable banana plug in black is an essential connector for anyone building reliable, flexible audio or electronic test setups. Designed to deliver secure, low-resistance connections, it allows multiple plugs to be stacked vertically, enabling efficient daisy-chaining of signals without the need for additional adaptors or messy wiring.

Ideal for use in laboratory test equipment, educational electronics projects, or high-quality speaker systems, this plug simplifies complex wiring arrangements. Its stackable design is particularly valuable when you need to connect several measurement instruments to a single point, or when configuring multi-way speaker crossovers and binding post terminations. The robust construction ensures repeated plugging and unplugging without loss of performance.

Technical features include a standard 4mm diameter plug that fits most binding posts and test sockets. The housing is made from durable black insulating material, while the contacts are gold-plated to resist corrosion and maintain optimal signal integrity over time. The internal solder terminal accepts cables up to a generous cross-section, providing a solid mechanical and electrical joint.

Whether you are a hobbyist building a custom amplifier or a technician maintaining professional audio gear, this stackable banana plug offers a practical, long-lasting solution for your connection needs.
