The Swing Clear Self-Closing Hinges by Waterson herald a new era in accessibility. Our L-leaf blade design ensures wider opening angles and an efficient self-closing feature. As Baby Boomers age, and ADA compliance is critical, our hinges are transforming lives by adding safety, door space and convenience.

Compliant with 3-hour fire rating and ADA requirements, these hinges facilitate door opening with under 5lbs of force and a controlled closing time over five seconds. Architects appreciate the combination of compliance and aesthetics.

Easy installation results in cost savings on maintenance and setup. Waterson's steel hinges embrace sustainability, being recyclable and utilizing 70% fewer materials than conventional options.

Waterson Swing Clear Hinges represent the future of door accessibility by merging innovation, user-focused design, safety, and eco-sustainability.

Founded in 1979, Waterson Corp. has been engaging in international trade of various special fasteners cold forging accessories. Beginning in 1989, we invested to construct a well-equipped factory for launching production in OEM parts, while simultaneously starting our R&D center for new products. Our efforts paid off later in 1991 when Waterson successfully marketed the SAFLOK Quick Coupler design, the SAFLOK Couplers always make the best safety guarantee for all people and environment; it also helped to resolve on-site work safety issues existing since long. We went on to establish a investment casting
factory in 1993 and started self-manufacturing the rough blank, in order to shorten the time needed for raw material supply while fully meeting quality requirements.


Founded in 1979, Waterson Corporation has more than 40 years experience in the investment casting business. Over that period of time, Waterson has earned over 100 utility patents, including SAFLOK coupling and W-LOK padlock, which are known industry-wide for their 10x safety. As a result, Waterson has become synonymous with precision, durability, and high-quality stainless steel manufacturing. In 2010, the company began developing the world’s first speed-adjustable self-closing hinges in order to solve the problem of hazardous door slamming. In 2015 Waterson Hinge became Asia’s first company to produce products that achieved the ANSI A156.17 grade 1 standard. Today Waterson’s innovative hinge design is chosen by architects and builders around the world. You can find Waterson hinges installed on commercial fire-rated doors, gates, and frameless glass doors from New York to Singapore to Dubai and beyond.
