The Simpson JB28 Top-Flange Joist Hanger for 2x8 Lumber is a cost-effective 18-gauge steel connector from Simpson engineered to provide reliable load-bearing support underneath joists, rafters, or beams for a strong, secure connection in solid sawn lumber framing applications. The JB series min/max nailing design gives builders the flexibility to match nailing patterns to actual load requirements, making this hanger a practical choice for a wide range of structural framing projects - from deck construction to floor framing and roof assemblies.

Key Features

• Min. nailing featuring positive-angle nailing targets moderate load conditions, whereas max. nailing generates capacities for higher loads - gives installers the flexibility to optimize the connection for the actual load demands of the project without switching to a different hanger.
• Unique two-level embossment on the top flange - provides added stiffness to the top flange, improving rigidity and overall connection strength where the hanger meets the header or beam.
• Sized for nominal 2x8 members - ensures a precise, snug fit for standard 2x8 joists, rafters, or beams, reducing installation guesswork and keeping framing aligned.
• Constructed from 18-gauge steel - delivers a reliable strength-to-material balance suited for typical residential and light commercial framing loads.
• G90 zinc galvanized coating - provides extra corrosion resistance, extending the service life of the connector in moisture-exposed framing environments such as decks, crawl spaces, and exterior structures.

Why This Product

• Built-in load flexibility without added complexity - the min/max nailing system lets you dial in the right capacity for moderate or higher load conditions using a single hanger model, reducing the need to stock multiple connector types for different applications.
• Engineered stiffness where it counts - the two-level embossment on the top flange adds structural rigidity at a critical transfer point, giving you a more stable connection at the header interface compared to a plain flat flange design.
• Corrosion-resistant finish for longer service life - the G90 galvanized coating is specifically suited for framing conditions where moisture exposure is a concern, helping the connector maintain its structural integrity over time without premature deterioration.
• Cost-effective solution from a trusted structural connector brand - the JB series is designed by Simpson as a value-oriented option within their broad hanger lineup, offering dependable performance for standard 2x8 joist hanger applications without paying for features you do not need.

Frequently Asked Questions

What size lumber is the JB28 designed to support?

The JB28 is designed for nominal 2x8 joist, rafter, or beam members in solid sawn lumber applications.

What nails should be used to install the JB28?

The JB28 should be installed with 16d common nails. Min. nailing is suitable for moderate load conditions, while max. nailing generates capacities for higher loads.

What gauge steel is the JB28 made from, and how is it protected against corrosion?

The JB28 is constructed from 18-gauge steel and features a G90 zinc galvanized coating, which provides extra corrosion resistance for long-lasting performance.

What is the purpose of the two-level embossment on the top flange?

The unique two-level embossment is designed to provide added stiffness to the top flange, enhancing the overall strength and rigidity of the connection.
