Product Description

The BEST 711068431 is a full-mortise commercial hinge built for steel and wood door applications in commercial settings. Constructed from steel with a primed finish and a stainless steel pin, this hinge is designed for durability in high-traffic environments. The 4.5-inch leaf height and 2-inch leaf width on both the door and frame leaves conform to standard commercial door prep dimensions. With 5 knuckles and a 360-degree range of motion, this hinge supports full swing in either direction, making it suitable for a wide range of commercial door configurations. It meets ANSI A156.1 and BHMA certification standards, confirming compliance with commercial door hardware specifications. Licensed locksmiths, door hardware installers, and general contractors typically specify and install this hardware.

This hinge is used in commercial door installations where a full-mortise mount is required, meaning both the door and frame leaves are recessed flush into mortised pockets. It is compatible with steel and wood doors and is suited for interior commercial applications such as office buildings, schools, healthcare facilities, and retail environments. The ANSI A156.1 and BHMA-certified class rating makes it appropriate for specification-grade projects that require documented hardware compliance.

Follow applicable building codes and hardware specifications for commercial door hardware when selecting hinge quantity and placement by door weight and frequency of use.
