Lift-Assist Torque-Adjustable Spring Hinge (HG-PA201-15)

This external surface-mounted heavy-duty power lift-assist hinge (Product No. HG-PA201-15) is a torque-adjustable spring hinge that makes heavy top-opening lids easy to open and provides smooth, soft-closing action to keep them from slamming shut. This heavy-duty spring hinge offers a damper torque of 15 Nm (153 kgf-cm) over a maximum opening angle of 100 degrees.

Like all Sugatsune products, our focus on product design delivers quality and durability. The construction of this lift-assist hinge features an SWO-grade steel spring and a 430 grade stainless steel hinge body, with a smooth plastic cover for a clean, neutral appearance.
