Description
The DELTANA MB175U15A is a mortise bolt designed for door hardware applications in residential and light commercial settings. It provides a flush-mount locking mechanism that installs directly into a routed mortise pocket in the door edge, allowing for a clean finished appearance without exposed hardware. The bolt ships as a single unit and carries an antique nickel finish. Overall dimensions are 3 inches in length, 2.1 inches in width, and 0.2 inches in height, making it a compact, low-profile component suited for interior doors, cabinet doors, and passage applications where a concealed bolt is required.
This mortise bolt is appropriate for interior door installations in residential homes, apartments, and light commercial buildings. It is typically installed on pairs of doors, French doors, and closet doors where a surface bolt is not desired. The antique nickel finish coordinates with a wide range of architectural hardware finishes. Installation is performed by a finish carpenter, millwork installer, or general contractor during door hardware rough-in or finish stages.
Key Features
- Antique nickel finish for a clean, period-appropriate aesthetic
- Low-profile 0.2-inch height for flush door-edge installation
- Compact footprint at 3 inches long by 2.1 inches wide
- Mortise-style mounting keeps hardware concealed within the door
- Sold individually, one bolt per order unit
Compatibility
Designed as an OEM-style mortise bolt replacement or new installation component suitable for standard interior door edges where a mortise pocket can be routed to the required dimensions.
Installation Notes
Installation requires routing a mortise pocket into the door edge to match the bolt body dimensions before setting the unit. All door work should be performed with the door removed or securely propped, and any associated latch or lock hardware should be fully disengaged before beginning. A licensed finish carpenter or qualified installer should verify that the door material and thickness are suitable for mortise routing. Follow local building codes for door hardware requirements in fire-rated or egress door applications.
