This is a 10-pack of the Small 4 mm right-angle mono plug. It fits Evidence Audio Monorail, Mogami 2314 and Blackrock (about 4 mm outer diameter). For cables around 5 mm such as Mogami 2319, choose the ESP Large (5 mm) instead.
Why players choose the ESP Plug
Builders choose the ESP plug when they prefer a soldered connection in a compact, low-profile package. It is a solderable pancake-style connector designed for clarity and clean assembly, sized to the outer diameter of your cable.
Honest note: the ESP plug requires soldering; choose the size that matches your cable's outer diameter.
How it compares
The ESP Small is the soldered pancake option for 4 mm cable such as Monorail bulk cable; the SIS plug is the solderless screw-in alternative for the same cable.
