HG-JHM Damper hinges series - Supported lid digest
● This table gives a general guideline of the different lid weight and measurements that can be used with HG-JHM series. ● Lid measurements have been calculated using the maximum torque available for the product model. (for example, for HG-JHM16 series we used HG-JHM16-50)
● The lid measurements are just an example of the various possible combinations of length, width and thickness. ● The torque value is calculated using one pair of HG-JHM installed on one lid.
