ABH N3331A Surface Mount Overhead Holder Stop - Medium Duty Adjustable, S4 (BSPC)The ABH N3331A Surface Mount Overhead Holder Stop is engineered for medium-duty applications, making it an ideal choice for moderate traffic doors. This adjustable mechanism allows for a field-adjustable opening range between 85° to 110°, providing flexibility for various usage scenarios. Designed with a friction function, the N3331A not only serves as a stop but also holds doors open securely, enhancing convenience in high-traffic environments.
Constructed from durable steel, this surface-mounted holder stop offers a robust performance, ensuring longevity and reliability in demanding conditions. The shock-absorbing spring feature delivers a smooth operation, cushioning the door movement by 3° to 5° before reaching a dead stop, thereby minimizing wear and tear.
The N3331A is non-handed, allowing for easy installation on either side of the door, and includes sex bolts for secure mounting on 1-3/4" to 1-7/8" doors. It is UL Listed for fire safety, accommodating 20-minute wood and 90-minute hollow metal door assemblies when used in stop function. Available in a variety of finishes, including S4 (BSPC), it can seamlessly blend with any interior design while meeting the stringent demands of architects, contractors, and facility managers.
