ABH N4423 Surface Mount Overhead Stop - Medium Duty, Bright BronzeThe ABH N4423 Surface Mount Overhead Holder Stop is an essential component for single-acting doors in commercial applications. This medium-duty surface-mounted stop not only provides reliable stop and hold-open functions but also offers friction control to accommodate varying traffic levels. Its robust steel construction ensures durability and longevity in high-use environments.
Designed for standard installations, the N4423 features a shock-absorbing spring that cushions the door movement, allowing for an opening range of 85° to 110° in 5° increments. This functionality is particularly beneficial in moderate traffic settings, where controlled door operation is critical. The non-handed design simplifies installation, making it an ideal choice for any door configuration.
The N4423 is UL Fire Door Listed, ensuring compliance with safety standards for wood and hollow metal door assemblies-providing a 20-minute and 90-minute fire rating, respectively, for the stop function. Finished in bright bronze, this model complements a variety of architectural styles, while additional finish options are also available to meet your design needs.
Included with the product are sex bolts suitable for 1-3/4" to 1-7/8" doors, facilitating a straightforward installation process. Experience the reliability and performance of the ABH N4423 in your next project.
