4mm Recessed Linear Slider / Fader Caps

4mm Recessed Linear Slider / Fader Caps

These distinctive fader caps feature a recessed linear design with a flat finger grip surface and a central coloured circle that serves as both an identity marker and position reference. The caps are designed with a clean, minimalist aesthetic where the position indicator line extends through the centre of the coloured circle, creating a clear visual reference for precise control adjustments.

The rectangular form factor provides excellent finger contact whilst the recessed design prevents accidental adjustment during performance or mixing sessions. Each cap incorporates a vibrant coloured accent that matches the position indicator line at its base, making channel identification quick and intuitive even in low-light environments. These caps are particularly well-suited for professional audio mixing consoles, DJ controllers, and broadcast equipment where precise fader control and visual feedback are essential for smooth operation.
