The Simpson HUC210-2Z is a heavy-duty, face-mount concealed-flange joist hanger engineered by Simpson for structures requiring additional strength and safety factors. Designed to support a nominal double 2x10 member, this hanger features concealed header flanges that deliver cleaner visible lines in exposed framing conditions - combining structural performance with a finished appearance. Built from 14-gauge steel with a ZMAX galvanized finish, it is purpose-built for exterior and treated-wood applications where enhanced corrosion resistance is essential. Compatible with wood, masonry, and concrete headers, it provides dependable versatility across a wide range of residential and commercial framing projects.

Key Features

• Concealed header flanges - keep flanges hidden from view in exposed conditions, delivering cleaner visible lines without sacrificing structural integrity
• 14-gauge steel construction - provides the heavy-duty strength needed for applications with elevated load and safety requirements
• ZMAX galvanized finish - offers extra corrosion resistance beyond standard galvanization, making this hanger well-suited for exterior environments and contact with treated wood
• Compatible with wood, masonry, and concrete headers - gives builders flexibility to use a single hanger solution across multiple substrate types
• Extra optional triangle holes - allow additional fasteners to be added when higher load capacity is needed on demanding jobs
• Tested, load rated, and code compliant - the HUC series meets recognized standards, supporting use in permitted construction with confidence
• Seat width of 3-1/8 in. - sized specifically for a double 2x10 joist, ensuring a proper fit and full bearing surface at the seat

Why This Product

• Built for demanding structural applications - the HUC210-2Z is specifically designed for structures requiring additional strength and safety factors, making it a reliable choice where standard hangers fall short
• Aesthetics and performance in one - concealed header flanges address a common challenge in exposed framing by maintaining cleaner visible lines without compromising load capacity
• Superior corrosion protection for harsh environments - ZMAX galvanization goes beyond standard coatings, making this hanger a practical long-term choice for exterior framing and pressure-treated lumber installations
• Versatile substrate compatibility - the ability to install double 2x10 joists into wood, masonry, or concrete headers reduces the need for multiple hanger types on mixed-material projects
