Adjustable Torque Plastic Hinge | Lightweight Free-Stop Door Hinge for Panels

Adjustable Torque Mechanism
The TOHUAS XK513 series features a user-friendly adjustable torque design. By simply turning the built-in screw, users can customize the rotational resistance to match the weight of the door or panel. This ensures a perfect free-stop experience, preventing doors from swinging shut unexpectedly.

High-Quality Engineering Plastic Construction
Made from durable engineering plastic (nylon), TOHUAS hinges are extremely lightweight (ranging from 16g to 46g). They offer excellent electrical insulation and resistance to corrosion and chemicals, making them ideal for environments where metal hinges might fail.

Arbitrary Angle Suspension & Positioning
Engineered with precision internal friction, TOHUAS hinges allow doors to stay firmly in place at any angle within their opening range. This "free-stop" capability eliminates the need for extra support stays, enhancing operational safety and convenience.

Versatile Specifications & Color Options
TOHUAS offers flexibility to suit various applications:

Multiple Sizes: Available in models XK513-1, XK513-2, and XK513-3 to fit different mounting hole distances and door sizes.

Color Choices: Comes in classic Black and White to seamlessly match the aesthetic of industrial enclosures, medical devices, or consumer electronics.
