Key Features

Supports the Joist

The Simpson Strong-Tie LUC26Z concealed-flange joist hanger carries the load under the joist instead of just tying into the side. That gives you a stronger-looking, cleaner connection for framing where exposed hardware would stand out.

ZMAX Protection

Built from 18-gauge steel with a ZMAX finish, this hanger is a solid pick for exterior work and treated lumber where corrosion resistance matters. If the connector is going into tougher jobsite conditions, that coating matters.

Hidden Flange Look

Concealed header flanges keep the side hardware out of sight, which is useful on decks, pergolas, and exposed framing. You still get tested, load-rated performance without the bulky look of a standard face-mount hanger.

Overview

The Simpson Strong-Tie LUC26Z concealed-flange joist hanger is a face-mount wood connector designed to support nominal 2×6 and 2×8 members. This is a joist hanger designed for supporting joists, rafters, or beams from a carrying member while keeping the header flanges hidden for a cleaner finished look. Model Number: LUC26Z.

What makes this hanger different from a basic face-mount hanger is the concealed-flange layout. Instead of leaving wide side flanges visible on the front of the carrying member, the LUC26Z keeps those flanges tucked back. On exposed framing, pergolas, and deck details where appearance matters, that gives you a much cleaner line without giving up a tested structural connection.

Simpson Strong-Tie builds the LUC26Z from 18-gauge steel and finishes it with ZMAX coating. In practical terms, that means the connector is made for real framing work and is better suited for exterior conditions and treated-wood applications than a plain unfinished hanger. If you are framing outdoors or working with pressure-treated lumber, the finish is not just a spec on paper, it is part of the reason to choose this exact model.

The hanger is load rated and code compliant, and Simpson publishes tested allowable loads based on the approved fastener schedule and wood species. For the LUC26Z, published values vary by fastener choice, with allowable loads reaching up to 1,300 pounds and uplift values up to 1,035 pounds when installed with specified Simpson Strong-Drive fasteners. That matters because you are not guessing what the hanger can do. You are working from an engineered connector with known performance.

Installation flexibility is another strong point. Simpson notes that the LUC series installs using several fastener selections with tested allowable loads, including Strong-Drive SD connector screws. That gives contractors options when they want a cleaner install, easier driving, or a fastening method aligned with the rest of the job. The published notes also call out that joists sloped up to 1/4:12 achieve table loads, and that end-grain nailing into a solid sawn carrying member requires an allowable-load reduction factor of 0.67. Those are the kinds of details that matter when you are building from plans instead of just hanging lumber by eye.

Dimensionally, the LUC26Z is sized for nominal 2×6 and 2×8 lumber, with a listed width of 1-9/16 inches, height of 4-3/4 inches, and seat dimension of 1-3/4 inches. That compact profile helps when you need concealed support without stepping up to a bulkier hanger than the application calls for. Lowe’s also lists actual dimensions at about 1.659 inches wide, 4.798 inches long, and 1.906 inches deep, which lines up with the published engineering table.

This connector is a strong fit for deck builders, carpenters, remodelers, and general contractors who want a structural hanger that does not draw attention to itself. It also makes sense for serious DIY users working on pergolas, porch framing, or repair work where exposed hardware would look out of place. If the job calls for a concealed-flange hanger for nominal 2×6 or 2×8 members, this is the right style of connector to be looking at.

Cleaner Exposed Framing

The concealed-flange design is the whole point here. You get the support of a face-mount joist hanger, but with a much cleaner look when the framing stays visible.

• Designed to support the joist, rafter, or beam from underneath
• Concealed header flanges reduce visible hardware in exposed conditions

Built for Exterior and Treated Lumber Work

This hanger is not just about shape. The 18-gauge steel body and ZMAX finish are what make it a practical connector for deck framing, outdoor repairs, and other treated-wood applications.

• Made from 18-gauge steel
• ZMAX coating adds corrosion resistance for exterior and treated-wood use

Multiple Approved Fastening Options

Simpson publishes tested allowable loads with more than one approved fastener schedule, which gives you flexibility without stepping outside the connector data. That is useful when you prefer structural connector screws over traditional nails.

• Published for specified Strong-Drive SD connector screw schedules
• Allowable loads vary by fastener choice and wood species

Simpson Strong-Tie LUC26Z Concealed-Flange Joist Hanger for Clean-Looking Framing

If you need a hanger that does the structural job without shouting for attention, this is the one to grab.

• Who it’s for: Carpenters, deck builders, remodelers, and serious DIY users framing with nominal 2×6 or 2×8 members where a cleaner finished look matters.
• Why it stands out: The concealed flange design looks better than a standard face-mount hanger, and the published load data plus approved fastener options make it a real structural connector, not just a cosmetic choice.
• Worth knowing: Fasteners are not included, so make sure you match the installation to Simpson’s specified schedule if you want the listed performance.

Common Questions

• What lumber sizes does the LUC26Z fit? It is sized for nominal 2×6 and 2×8 members.
• Is this hanger suitable for exterior or treated-wood applications? Yes. The ZMAX finish is intended to provide extra corrosion resistance for exterior and treated-wood use.
• Can this hanger be installed with connector screws? Yes. Simpson publishes tested allowable loads for specified Strong-Drive SD connector screw schedules, including SD9112 and SD10112 options.
• Are the flanges visible from the front? No. This is a concealed-flange face-mount hanger, so the header flanges are hidden for cleaner visible lines in exposed conditions.
