For lightweight fittings in bathrooms, horizontal type for bathrooms with door weights of 10-30kg, 30-60kg and 60-80kgNSC-CB23 36 48NSseries The use of stainless steel and a unique sealing technology has created corrosion- resistant, long-life products. Features 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.
