4003 Treble Bezel Cove in light textured black. Cove has a recessed pocket for thumb anchoring.

4003 series have a stepped down center to follow the contours of the stepped down center of the factory chrome surround. These will fit into earlier 4001 straight across surrounds, but a 4001 Specific Treble Bezel will look nicer in a 4001 straight surround.
