Counterbalance Support Hinge

Southco, Concordville, PA, has released a counterbalance support hinge that reduces the total cost of lifting and positioning heavy panels and lids. The support hinge is designed to be used in tandem with the CB counterbalance hinge in applications where the counterbalance hinge can support the full torque requirements of the panel or lid on its own. The support hinge enables ergonomic lifting and position control when combined with a counterbalance hinge by using stored energy to balance the weight distribution of a lid or panel. The hinges are fully adjustable, allowing the experience of opening and closing the panel to be tailored to the unique requirements of the application.
