Simpson Strong Tie DTT1Z Zmax Deck Tension Tie

Product Description

The SIMPSON STRONG TIE DTT1Z is a 14-gauge galvanized steel tension tie designed to resist lateral and uplift forces at deck railing post connections and joist attachments. The ZMAX coating provides enhanced corrosion resistance compared to standard G90 galvanizing, making this connector well-suited for exterior applications exposed to moisture and treated lumber. It ships in packages of 40 units and is installed by framing contractors, deck builders, and licensed carpenters working on residential or light commercial wood-framed deck structures. The DTT1Z transfers tension loads between deck framing members and ledger or rim board connections, contributing to the overall structural integrity and code compliance of the assembly.

The DTT1Z is used in wood-framed deck construction where building codes require positive connections at railing posts, joists, or beam-to-post interfaces. It is applicable in residential deck builds and remodels where lateral load transfer and uplift resistance are specified by local building departments or project engineers. The ZMAX finish makes it compatible with ACQ, CA, and other preservative-treated lumber products that are corrosive to standard hardware.

Key Features

• 14-gauge galvanized steel construction for structural-grade load capacity
• ZMAX coating provides elevated corrosion resistance for use with treated lumber
• Designed to resist tension, lateral, and uplift forces at deck connections
• Sold in packages of 40 for project-quantity purchasing
• Compact connector profile installs with standard fasteners in typical framing cavities

Compatibility

Designed as an OEM-style structural connector for use in wood-framed residential deck construction where tension tie hardware is required by code or engineering specification.

Installation Notes

Installation is performed by framing contractors or licensed carpenters in accordance with local building code and the IRC or IBC as applicable. Power down any adjacent low-voltage lighting or electrical runs before fastening in confined joist bays. Use only the fastener type and quantity specified on the connector label or in the manufacturer load table — substituting fastener size or count affects the rated load value. Do not modify or bend the connector in the field.
