Damper Hinge HG-JHM20
The LB-350 locking stay here is being used to keep the lid of a chart table open, it has a lift up to release mechanism for closing. Whilst the LB-350 is an effective solution, in the next picture the an NSD-20 damped lid stay is being used. Many yacht manufacturers are opting for dampening mechanisms because they combine safety features with a luxury silent movement.
The NSD is a stalwart of the Sugatsune product range but keeps selling because it is incredibly reliable and does it’s job well. The NSD-20 will keep the lid open and also adds soft closing. It is seen here combined with a simple concealed hinge.
A damper hinge plus a rotary torque
Installing torque hinges or stays is straight-forward enough but requires a calculation to work out the torque moment of the door. If you’re an engineer it’s the work of a moment (pun intended) for the rest of us Sugatsune have an easy to use torque calculator on their website. You’ll need to know the material, thickness, height and width of your door which you enter into the appropriate boxes. The calculator will then tell you the torque moment and also will suggest Sugatsune products that fit within this torque range. You can further refine your search by choosing the orientation of the door you are using.
“We’ve had many compliments about the Torque Calculator” Mike Rogers says ” It can even be used to calculate the moment of composite doors if you know the overall weight. Just put in the dimensions and increase the thickness of the material until you hit your weight. The correct torque values are then displayed.”
