According to NY Daily News, New York landlords are required to install self-closing spring hinges to prevent the deadliest Bronx apartment fire from happening again. Many owners chose spring hinges as their self-closing door solution. While both conventional spring hinge mechanisms and Waterson Closer Hinges have the same advantage – self-closing functionality, Waterson stainless steel spring hinges actually sustain longer, adjust easier, and can be used on both interior and exterior openings.
Sustain Longer
Some of the common spring hinges employ the design for use on medium heavyweight doors and medium frequent usage applications. However, Waterson’s self-closing mechanism passed UL-certified one million cycle testings. they also can be applied on extremely heavyweight doors (260-440 lbs) with high-frequency usage. Besides, our high-grade 304, 316 stainless steel spring hinges ensure resistance to scaling at elevated temperatures and maintain toughness at cryogenically low temperatures.

Adjust Easier Without Door Slam
Unlike most spring hinges, Waterson’s VISUAL numerical tension panel and patented speed control unit make the adjustment process much more assured and precise. Installers can effortlessly use the installation kit we provide to achieve the ideal tension based on different environments or user needs. At the end of the day, you have a clean-looking, speed-controlled, self-closing door.

List of the Installation Kit
- Both machined #12-24 UNC ½” L and wooden tapping #12 x 1 ¼” screws included — eight (8) of each type per hinge.
- The pack contains five (5) spares as well.
- Three steel adhesive shims for gap adjustment between door and frame as needed
- Tension Crook: Keeps hinge open during installation
- 5mm & 3mm hex allen wrenches
Interior & Exterior
Exterior doors, by definition, are the doors to enter or leave a building. Due to the new law enforcement in New York City, every entry door and exterior door needs a self-closing mechanism. However, most spring hinges do not have the design to be used on these doorways.
On the other hand, Waterson stainless steel spring hinges can be installed both indoors and outdoors. They can readily resist harsh environments and perform auto door closing features consistently.

According to NFPA 80, section 6.4.3.4, only steel shims are acceptable for fire-rated door assemblies. Therefore, Waterson offers stainless steel spring strips for doors, which are metal door shims. They are suitable for all conditions and requirements, including fire-rated and even corrosion environments.
Most stainless steel is Grade 304, which is well-known for corrosion resistance, formability, strength, and easy maintenance. Grade 316, though less common, offers superior resistance to chlorides and acids and is considered the best type.

Waterson spring hinges have dual functions: spring tension for closing and swing speed for adjusting the closing speed. They come in six types (DS, SA, SA1, HS, SB, HA) to suit different needs. Each hinge includes two functions: spring power, swing speed, latch speed, hydraulic buffer, and hold open.
