Waterson hinges perform best in a swing zone from 0˚ to 120˚. Whereas our hydraulic hybrid hinge open limit is 120˚, the mechanical can be opened beyond 120˚up to 180˚. That said, we do not suggest keeping the mechanical over 120˚ for long periods of time; frequently extending beyond 120˚ will damage the mechanism and decrease its lifespan. Please note that excessive use over 120˚will not be covered by warranty.
