Inspection ports and gas chambers quietly play a leading role! Hinge series.

It does not compromise the design of the door. A hidden gem.

The concealed hinges quietly excel in facilities such as office buildings, commercial spaces, and apartment complexes. By installing them on the back side of the door, you can maintain the design integrity of the door while presenting a clean surface. The B-160 series offers a variety of options, including standard types, stainless steel versions, and those compatible with overlay doors, allowing you to choose hinges that suit your needs. We also provide self-closing types with springs that automatically close the door. ● Improved work efficiency on-site The rivet design prevents the pin from falling out, ensuring that the axis and wing body remain together, and it can be installed without regard to left or right, allowing for speedy progress in work. ● Dimension design that eliminates the need for a 2.3mm liner The specifications that do not require a 2.3mm liner save the hassle and cost of installing a liner. While reducing effort, costs, and waste, it still provides the same strength as when a liner is installed. Additionally, by using our pivot hinges in conjunction, you can prevent door warping and accommodate large doors (door size H2100 or more). *Please contact us separately for more information. We invite you to try our concealed hinge series!
