"The perfect head right out of the box and onto the field."
Crimplock™ heads feature a profiled hoop design which provides better tuning capability at higher tensions. The outer edge of the hoop is profiled over the glue channel, creating rigidity and higher strength. These heads are typically found in drum corps, pipe band and marching applications. Crimplock™ is only offered on heads 22" and smaller.
WeatherKing® Open Channel Hoops (Non-Crimplock) are ideal for most playing situations where the drumhead is free to stretch and vibrate in relation to a wide range of playing styles and tunings.
