ABH N4421 Surface Mount Overhead Stop - Medium Duty, Bright Stainless SteelThe ABH N4421 Surface Mount Overhead Holder Stop is a medium-duty solution specifically designed for single acting doors in commercial environments. This versatile hardware offers essential stop, hold-open, and friction functions, making it ideal for moderate traffic applications. Crafted from durable steel, the N4421 features a bright stainless steel finish (US32) that not only enhances its aesthetic appeal but also ensures long-lasting performance.
Engineered for reliability, the surface-mounted design allows for straightforward installation on doors ranging from 1-3/4" to 1-7/8" thick, with included sex bolts for secure attachment. The shock-absorbing spring provides a smooth operation, cushioning the door’s movement with a 3° to 5° cushion before reaching the dead-stop position, thus protecting both the door and surrounding structures.
In addition to its practical features, the N4421 is UL Fire Door Listed, ensuring compliance for use with 20-minute wood and 90-minute hollow metal door assemblies when employed in the stop function. With an operating range of 85° to 110° in 5° increments, this non-handed design offers flexibility and ease of use across various commercial applications.
