Kason 1248 Spring Assisted Hinges, Pack of 2, Flush Offset

The spring mechanism in this system adds an extra closing force, which helps to overcome the air resistance encountered with heavy walk-in doors. This specialized mechanism outperforms similar spring hinges, thanks to its high-lift cam system.

The cam-rise action of this design reduces wear on the gasket, even in the presence of irregular floors. This is a significant benefit, as it helps to maintain the integrity of the door's seal over time.

Another notable feature is the built-in dwell, which holds the door open beyond approximately 135 degrees. This allows for more convenient access and passage through the doorway.

The simple manual operation of this system also allows for the hinges to be easily reversed, enabling the door to be used for both right-opening and left-opening applications. This versatility adds to the overall usefulness and flexibility of the design.

In summary, this spring-based mechanism offers several key advantages over traditional hinge systems. The added closing force helps to overcome air resistance, while the high-lift cam design outperforms standard spring hinges. The cam-rise action reduces gasket wear, even on uneven floors, and the built-in dwell holds the door open for convenient access.

Lastly, the ability to easily reverse the hinges for left- or right-opening doors adds to the overall versatility and practicality of this system. These features combine to create a reliable and user-friendly solution for heavy, high-traffic walk-in doors.
