Frequently asked questions and answers on our easy-to-use and durable Waterson Hinges

Most high-demand items ship from our Georgia, Michigan, and California-based warehouses, however, urgent orders and large quantity items are stocked and fulfilled from our headquarters in Taiwan.  Shipping from Taiwan is rather quick and seamless, perhaps even more efficient than from US-based Amazon or other 3rd party warehouses.  We use expedited freight forwarders like FedX and UPS, so the shipping time from Taiwan is not long at all.  The lanes between Taiwan and the United States are quite active, so freight moves daily between the two countries.  Plus, with the time difference, we can process your order immediately and have it in transit while you sleep.  In terms of pricing, we only charge the domestic transportation fee, so your price is not affected by international shipping rates.

At this time we only provide self-closing closer hinges for vertical doors. 

It’s not leaking. Don’t worry, we simply added a bit of lubricant between the washers to improve initial performance. After a brief period of time the inner components will become smooth after the hinge breaks in. Self-closing performance will not be hindered in any way.
Simply wipe the lubricant with a soft cloth.

Waterson hinges can be both in-swing and out-swing, however, the fastening screws will always be facing on the in-swing side.

Waterson hinges are non-handed and can be inverted as needed. View this drawing to learn more.

This feature holds the door open at 90 degrees, and it only contains the door temporarily. With a light push of the door to below 80 degrees, the self-closing feature takes over and closes the door. Also, it doesn’t stop the door from opening too wide.

Unfortunately, the hold-open feature does not coexist with fire-rated doors.

Waterson Closer Hinges are all non-handed design.

Hydraulic hinges have a buffering feature that allows the door to close even slower when entering a certain angle, can only use on the door that opens ≤ 120° and at temperature > 32°F (0°C)

Mechanical hinges set (A3, A4) perform self-closing functions for frequently used doors, it is quiet but not as quiet as the hydraulic hinges (B3, B4). For further information please see this Solution page.

Due to the unpredictability of outdoor conditions, we do not suggest to use hydraulic hinges on exterior gates. Because our hydraulic closer hinges only work on a certain degree of the door opening (≤ 120°) and the limitation of temperature[> 32°F(0°C)]

No, that is just a precaution to prevent the hinges from being easily damaged in the future. It will not damage directly, but it does make the hinge more prone to damaging, which lessens the lifetime of the hinge.

Yes, we do, our installation kits include screws for wooden and metal doors, shims to adjust the gap between the door and the frame, and an allen wrench for tension adjustment.

Waterson hinges work as a system; each hinge provides a different closing and speed control function. In theory, you could combine Waterson hinges with other ANSI 156.7 compatible hinges, however, we cannot guarantee the function and longevity in such a circumstance. Therefore we would not be able to honor the warranty. We recommend only using a set of Waterson hinges on any particular door.

Yes. Waterson hinges are perfect for outdoors, We usually provide K51MP for exterior use.

Follow the ANSI standard, the door below 7″ needs 3 hinges and the door below 8″ needs 4 hinges. Please take a look at this Configuration Sheet.

Both of them hold the same weight. It is based on the size of the door, depending on your application it is possible to use 2-4 hinges on a door.

We do offer 316 marine grade stainless steel, but it requires longer lead time.

Yes, Waterson hinge meets the USA standard (ANSI/BHMA A156.7, Template Hinge Dimensions) Therefore, you can safely replace the existing hinges with Waterson hinge.

We do, but we only offer this option to the customer who purchases self-closing hinges from us. Please Contact Us if you need any further assurance.

Waterson hinges perform best in a swing zone from 0˚ to 120˚. Whereas our hydraulic hybrid hinge open limit is 120˚, the mechanical can be opened beyond 120˚up to 180˚. That said, we do not suggest keeping the mechanical over 120˚ for long periods of time; frequently extending beyond 120˚ will damage the mechanism and decrease its lifespan.  Please note that excessive use over 120˚will not be covered by warranty
