According to NFPA, a fire-rated door must be self-closing, and the door must close when released from a fully open position. Additionally, some codes and standards require the door to close and latch when released from as little as 30 degrees. Typical spring hinges struggle to achieve this requirement, so most builders choose traditional door closers to satisfy. However, standard door closers tend to be bulky, unsightly and create a rather cold institutional feeling.
Waterson Hinges are increasingly being chosen on building projects, as they not only satisfy fire-rated code requirements but also provide a pleasant aesthetic — many Waterson customers have commented that they appreciate the tidy look both inside and out. In terms of power, Waterson hinges easily close and latch from as little as 20 degrees, which more than satisfies NFPA requirements. This ensures reliable and safe closing.
