A Dual-Axis Folding Hinge for Table Extensions & Trays

The HG-TMH Series folding hinge for table extensions and trays provides one amount of torque or friction for the first 90° and another for the second 90° to ensure smooth movement throughout the entire 180° travel. We designed it to conceal the shafts when the hinge is fully opened or closed while providing stability and premium quality for applications in shops, trains or airplanes.

  • Fold down trays and tables
  • Multifunctional workstations

This model is HG-TMH2030-BL, which has a Black finish and Shaft A torque of 20.4 kgf⋅cm (2 N⋅m). Shaft B provides torque of 30.6 +/- 20%.

Choose from Different Finishes & Torque Strengths

We also have this black dual-axis friction hinge available in a Chrome or Satin Nickel finish, and all three finishes are additionally available in a variant with a lower Shaft A torque of 15.3 kgf⋅cm (1.5 N⋅m).

With six different options to choose from with our HG-TMG folding hinge for table extensions and trays, you are sure to find just the right look and function for your project’s needs!


An Elegant, Fully Concealed Torque Hinge

The HG-TMH Series folding tray table friction hinge is designed both for performance and a clean, minimalist appearance.

When fully opened or closed, the hinge is completely flat and flush with the ends of the folding table pieces. This gives a cleaner look and is also safer, reducing accidental bumps and scrapes. The hinge is designed so that the screws are fully concealed when the hinge is closed.

When opening or closing the folding piece, each hinge operates one-at-a-time thanks to different torque ratings. This improves safety and contributes to ease of operation.

Free-Stop Motion for Full Positional Control

As a torque hinge, you have full free-stop motion control with the HG-TMH Series folding hinge for table extensions. In addition to the open and closed positions, you can safely leave the folding piece in any intermediate position.

Another benefit of the torque on this folding tray table friction hinge is that, together with the dual-axis design, it’s more comfortable to open and close the folding piece, as our design avoids the wobbly, jerky motions of conventional 180° hinges.
