664 Gas springs, stainless steel hardware 38 \ 38.832.01/05 \ 38.832.07 \ 38.832.07 Self-supporting hinge AISI 316 FRICTION HINGE Made of precision-cast AISI 316 stainless steel. Constant torque 30 kg·cm ± 15% guaranteed for 20,000 cycles. The torque is expressed in kg·cm,, meaning that departing from the hinge rotation axis, the effort decreases. Torque calculation: hatch depth (cm) x 1/2 hatch weight (kg). Example: 2x 30-kg hinges perfectly hold a hatch 2-kg heavy and 40 cm deep.

For use with standard double pin hinges (not self-supporting). The choice of the proper hinge depends on the weight of the foldable door: If 2 self-supporting hinges generate a too high load, only one is used plus a non-self-supporting hinge.
