  • Golf club head with adjustable weight
    Patent number: 10213665
    Abstract: The invention provides a golf club head with a lid or cover enclosing a recess such as a channel for an adjustable weight. A golf club head can include a multi-position weight track or other channel or concavity to house a feature such as an adjustable weight mechanism. The club head has a lid that covers the channel, which—when closed—provides an outer surface of the golf club head that does not collect dirt or make whistling sounds when used and thus removes distractions and maintains the club head's intended weight distribution.
