The Simpson Double 2-5/16 x 16 Concealed-Flange Heavy Face-Mount Hanger is an engineered structural connector designed for heavy timber and engineered lumber framing applications that demand additional strength and elevated safety factors. Built for both residential and commercial construction, this heavy-duty face-mount joist hanger accommodates double-member joist configurations at a 2-5/16 x 16 seat, while its concealed header flanges keep structural connections clean and unobtrusive in exposed framing conditions.

Key Features

• Concealed Header Flanges - Hidden from view once installed, these flanges deliver clean visible lines in exposed framing conditions where the appearance of structural connections matters to the finished result.
• Heavy-Duty 14 ga. Steel Construction - The robust 14 ga. (68 mil) material provides the load capacity needed for heavy timber connections and structures with elevated load requirements where standard hangers are insufficient.
• Face-Mount Installation - Attaches directly to the face of the header or beam, making this hanger a practical choice for a wide range of residential and commercial framing layouts without requiring modifications to the primary member.
• Double-Member Seat Configuration - The 2-5/16 x 16 seat is sized specifically for double-joist applications, ensuring a secure, properly fitted connection for engineered lumber and heavy timber framing members.
• Galvanized Finish - Provides a protective coating suited for structural connector applications, helping maintain the integrity of the connection over the life of the structure.
• Simpson Engineering and Quality - Backed by the trusted Simpson name, this connector is purpose-built for applications where structural reliability and consistent performance are non-negotiable.

Why This Product

• Built for demanding structural loads - This heavy face-mount hanger is specifically approved for applications requiring additional strength and safety factors beyond what standard joist hangers provide, making it the right choice for heavy timber and engineered lumber framing where load requirements are elevated.
• Aesthetics and performance in one connector - The concealed header flanges serve a dual purpose: they meet the structural demands of heavy framing while keeping connections visually clean in exposed conditions - an advantage on projects where the framing remains visible in the finished space.
• Versatile across project types - Approved for use in both residential and commercial construction, this hanger suits a broad range of face-mount joist and beam connection scenarios, reducing the need to source multiple connector types for different phases of a project.
• Domestic manufacturing from a recognized brand - Produced in the United States by Simpson, this connector reflects the consistent material standards and engineering oversight that structural professionals rely on for critical load-bearing connections.
