The Simpson LTHMA Light-Duty Multiple-Truss Hanger is a purpose-built connector from Simpson designed to support two or three single-ply trusses in terminal hip roof installations. Engineered for hip truss configurations where trusses meet at a 45 deg. angle, this hanger addresses one of the more demanding conditions in residential and light commercial roof framing - delivering dependable load transfer right where complex truss geometry converges.

Key Features

• Multiple-Truss Capacity - supports two or three single-ply trusses from a single connector, reducing the number of individual hangers needed in a terminal hip layout and simplifying the overall framing assembly
• Terminal Hip Configuration Support - engineered specifically for trusses positioned at a 45 deg. angle, so the connector geometry aligns naturally with hip roof framing without requiring field modification
• 16-Gauge Steel Construction - provides consistent structural rigidity suited for light-duty truss applications where a reliable, repeatable connection is essential
• Galvanized Finish - delivers corrosion resistance that helps the connector hold up in typical roof framing environments over the life of the structure
• Girder Truss Compatibility - accommodates both 2x4 and 2x6 bottom chord girder trusses through straightforward hole-filling requirements, giving installers flexibility across common framing dimensions
• Domestic Manufacturing - produced in the United States, supporting consistent quality standards and reliable material sourcing

Why This Product

• Solves a Specific Framing Challenge - terminal hip installations require a connector that handles converging trusses at a precise 45 deg. angle while distributing load symmetrically, and the LTHMA is purpose-designed for exactly that condition rather than being a general-purpose hanger pressed into service
• One Connector, Multiple Trusses - the ability to carry two or three single-ply trusses from a single hanger reduces hardware count at a critical junction, keeping the connection point clean and the installation straightforward
• Versatile Across Common Chord Sizes - compatibility with both 2x4 and 2x6 bottom chord girder trusses means the same hanger works across a wider range of hip roof framing scenarios without substituting parts mid-job
• Trusted Simpson Engineering - backed by Simpson's established reputation in structural connectors, the LTHMA gives builders and inspectors a recognized, specification-friendly solution for terminal hip truss applications

Specifications

Frequently Asked Questions

How many trusses can the Simpson LTHMA support?

The LTHMA is designed to carry two or three single-ply trusses in a terminal hip installation.

At what angle are the hip trusses set when using the LTHMA?

Hip trusses are positioned at 45 deg. in a terminal hip installation using the LTHMA hanger.

What gauge steel is the Simpson LTHMA made from?

The LTHMA is fabricated from 16-gauge steel with a galvanized finish.

What hole-filling requirements apply when used with girder trusses?

For girder trusses with 2x4 bottom chords, fill the round holes. For girder trusses with 2x6 bottom chords, fill both the round and triangle holes.

Always consult applicable local building codes and a qualified structural engineer before installation. Follow all manufacturer installation guidelines to ensure proper performance of this connector.
