*The thickness that can be screwed will vary depending on the hardness of the cable.

These are ONKODO unpainted, non-plated banana plugs.
This is a larger diameter model of our currently very popular BP-146B.
This can accommodate thicker cables up to 5φ that could not be accommodated in the BP-146B.

Non-plated brass body with a straight sound and contact pins only
Phosphor bronze is used. It has electrical conductivity close to that of copper and maintains high electrical conductivity.
The shell body is also made of brass and is unpainted to prevent the deterioration of sound quality that can be caused by painting.

As shown in photo 2, the products are shipped and stored individually packaged from the factory, so their quality is maintained.
We can deliver it to you. Copper is prone to rust, but if you insert it, the contacted part is less likely to rust.
In addition, since it is a BFA type, the pin part can be easily polished.
Please try our non-plated banana plugs, which are designed with a focus on sound quality.

*Brass is 70% copper, while phosphor bronze is over 90% copper, so you can expect high electrical conductivity.
