The Simpson Strong-Tie LTTP2 Light Tension Tie is built to resist tension loads when connecting wood to concrete or masonry walls, making it a reliable choice for both horizontal purlin connections and vertical holdown applications. Constructed from 10-gauge steel with a G90 zinc galvanized finish, this tension tie delivers durable structural performance in demanding conditions. Its dual nailing patterns and extruded anchor bolt hole support a range of common installation scenarios, from I-joist purlins to 2x solid-sawn purlins, giving contractors and builders the flexibility to work efficiently across multiple application types.

Key Features

• Two separate nailing patterns (obround holes for I-joist purlins, square holes for 2x solid-sawn purlins) - lets you use a single connector across different wood member types without compromising the connection, reducing the need to stock multiple hardware styles.
• Extruded anchor bolt hole compatible with 1/2 in., 5/8 in., and 3/4 in. bolt diameters - accommodates a range of anchor bolt sizes so the tie can be matched to code-required applications based on the substrate being used, including unreinforced concrete masonry.
• Low-profile seat design - keeps the tie visually discreet once installed, which matters in applications where exposed hardware is undesirable.
• G90 zinc galvanized coating - provides extra corrosion resistance, supporting long-term performance in exposed or moisture-prone environments.
• Compatible with nails or Strong-Drive SD Connector screws - gives installers the option to fasten with the hardware they have on hand, adding jobsite flexibility.
• Suitable for both horizontal purlin and vertical holdown applications - a single connector that can be installed on the wide face of a minimum 2x4 stud for holdown use, extending its utility beyond purlin connections alone.

Why This Product

• Versatile across purlin types and anchor bolt sizes - the dual nailing pattern layout and multi-diameter anchor bolt hole mean this tension tie adapts to I-joist purlins, 2x solid-sawn purlins, and varied bolt sizes, reducing the number of separate connectors needed on a project.
• Built for real-world code compliance - tested with different anchor bolt diameters to meet code-required applications based on substrate, including support for 3/4 in. post-installed anchor bolts in unreinforced concrete masonry walls.
• Durable enough for exposed conditions - the 10-gauge steel construction combined with a G90 zinc galvanized finish gives this light tension tie the corrosion resistance needed for applications where moisture exposure is a concern.
• Doubles as a holdown connector - when installed vertically on the wide face of a minimum 2x4 stud, the same tie used for purlin work can serve holdown applications, making it a practical choice for projects requiring both connection types.

Frequently Asked Questions

What anchor bolt diameters are compatible with the LTTP2?

The LTTP2 features an extruded anchor bolt hole designed to accommodate 1/2 in., 5/8 in., and 3/4 in. bolt diameters, giving installers flexibility to meet code-required applications based on the substrate being used.

Can the LTTP2 be used for both purlin and holdown applications?

Yes. The LTTP2 is designed primarily for horizontal purlin applications but may also be installed vertically on the wide face of a minimum 2x4 stud for holdown applications.

What are the two nailing patterns on the LTTP2, and when should each be used?

The LTTP2 features obround holes spaced 3 in. apart, intended for I-joist purlin connections, and square holes spaced to accommodate the narrow face of 2x solid-sawn purlins. Selecting the correct pattern depends on the purlin or rafter type being fastened.

What fastener types can be used to install the LTTP2?

The LTTP2 can be fastened with nails or Strong-Drive SD Connector screws. Specific nail options include (12) 0.148 in. x 1-1/2 in. nails or 0.148 in. x 2-1/2 in. nails into the obround holes, or (15) 0.148 in. x 2-1/2 in. nails into the square holes, along with one anchor bolt in the specified diameter.
