Best 711053870 Full Mortise Concealed Hinge Steel Primed

Product Description

The BEST 711053870 is a full mortise concealed hinge designed for commercial and residential door installations requiring a clean, flush-mounted appearance. Built from steel with a primed finish, this hinge features a 5-knuckle design and a non-removable pin for added security. It measures 4 inches overall width with a 4.5-inch leaf height on both the door and frame sides, and a leaf thickness of 0.134 inches. The primed surface accepts paint for a finished look. Licensed door hardware installers and commercial carpenters are the primary trades that work with this component.

This hinge is suited for full mortise door applications where both the door leaf and the frame leaf are recessed into the door edge and jamb. It is appropriate for interior commercial doors, institutional settings, and residential applications requiring ANSI A8133 and BHMA compliant hardware. The 4-inch overall width and 2-inch leaf width on both door and frame sides make it a standard fit for typical hollow-metal and solid-wood door frames in commercial construction.

Key Features

• Full mortise mount type — both leaves recess flush into door edge and frame jamb
• Non-removable pin design adds resistance to forced-entry hinge-side attacks
• 5-knuckle configuration provides stable pivot support across the door leaf height
• Steel construction with primed finish — paintable to match door and frame finish
• Meets ANSI A8133 and BHMA standards for door hardware
• Class 179F designation per manufacturer specification

Compatibility

Installation Notes

Installation requires precise mortise routing into both the door edge and the door frame jamb to achieve a flush-mounted fit. Power down any electric strike or access control hardware integrated into the door before beginning work. A qualified door hardware installer or finish carpenter should verify door prep dimensions against hinge leaf size before cutting mortises. Follow applicable local building codes and ANSI hardware guidelines for commercial door installations.
