Control device

Release the door, and it will automatically close gently and slowly.

Model

D : Inclined N : Horizontal

Door weight

The control device incorporates a fluid friction resistance, one-way clutch mechanism to ensure secure control, small size, and a long service life.

Long service life

Since door resistance is low, the door can be opened easily even by elderly citizens, young children, and people with disabilities.Initial door-opening force at a door weight of 40kg DSC-C08 type, 6.7N; NSC-C36 type, 5.7N

Light door-opening force

The only modifications made on the frame are the making of rail-mounting holes. All parts can be installed on the rail with a screwdriver. The product is therefore easy to install.

Easy to install

The product can be converted between the right- and left-handed opening types by a simple operation.

Both for right- and left-handed open

Many models designed for wooden, steel, and aluminum fittings.The options available are interlocking system and shutter boxtype.

These products can be used for long periods even in bathrooms and other hot corrosive environments. (They cannot be used in sauna rooms or other very hot environments.) The rotary part of the door roller is so designed as to be independent of dust or moisture, thus ensuring high corrosion-resistance and long stability.These products apply to doors weighing 10-80kg with openings not exceeding 1,500mm.The control device consists of a controlling-force centrifuge structure based on fluid friction resistance, thus ensuring high reliability.These products use a pull spring giving excellent performance and high durability (1 million operations) to close the door securely with a light force.

The use of stainless steel and a unique sealing technology has created corrosion-resistant, long-life products.

For lightweight fittings in bathrooms, horizontal type for bathrooms with door weights of 10-30kg, 30-60kg and 60-80kg
