ABH N4012 Concealed Mount Overhead Holder Stop - Medium Duty Hold Open, Bright ChromeThe ABH N4012 Concealed Mount Overhead Holder Stop is engineered for medium-duty applications, delivering exceptional performance for both single and double-acting doors. With its innovative concealed mount design, this holder stop provides a sleek aesthetic while ensuring reliable functionality in commercial environments experiencing moderate traffic.
Constructed from durable steel, the N4012 features a shock-absorbing spring that cushions the door's movement, providing a 3° to 5° cushion before reaching a dead stop. This ensures smooth operation while protecting door frames and hinges from wear. The overhead holder stop supports stop, hold-open, and friction functions, making it versatile for various applications.
Compliance is assured with its UL listing for fire door assemblies, applicable to both 20-minute wood and 90-minute hollow metal door assemblies for the stop function. The bright chrome finish (US26) offers an attractive and corrosion-resistant surface, enhancing the product’s longevity and suitability for both interior and exterior use.
Designed for doors with a minimum thickness of 1-3/8", the N4012 operates within an opening range of 85° to 110° in 5° increments. This non-handed design is ideal for facility managers, architects, and contractors seeking reliable and aesthetic door hardware solutions.
