Simpson Strong Tie DTT1Z-KT Deck Tension Tie Kit

Product Description

The SIMPSON STRONG TIE DTT1Z-KT is a ZMAX deck tension tie kit designed to reinforce deck structures against lateral and uplift forces. Built from 14-gauge galvanized steel with a ZMAX coating, these tension ties are suited for outdoor applications where moisture and corrosion resistance are critical. The kit ships as a unit of 4 ties and includes the necessary fasteners for a complete installation. This product is installed by licensed contractors, carpenters, and structural technicians working on residential and light commercial deck framing.

This tension tie kit is used in deck-to-ledger and post-to-frame connections where code-compliant structural reinforcement is required. The ZMAX galvanized coating makes it appropriate for ground-contact and pressure-treated lumber applications where standard galvanizing may not provide sufficient corrosion resistance. Typical installations include exterior decks attached to residential structures, where local building codes mandate positive connection hardware at key structural joints.

Key Features

• 14-gauge galvanized steel construction with ZMAX coating for enhanced corrosion resistance
• Kit includes 4 tension ties plus all necessary fasteners
• Designed for deck structural reinforcement at lateral and uplift connection points
• Compatible with pressure-treated lumber commonly used in exterior deck framing
• Packaged as a single unit (EA) for straightforward quantity management on the job

Compatibility

Designed as an OEM-style structural connector for use in residential and light commercial deck framing applications requiring tension tie hardware at code-mandated connection points.

Installation Notes

Installation should be performed by a qualified carpenter or contractor in accordance with local building codes and the International Residential Code (IRC) structural fastening requirements. Ensure all framing lumber is properly sized and that the deck structure is plumb and square before installing tension ties. Use only the fasteners included in the kit or those specified in the manufacturer load tables — substituting fastener types can void listed load values. Do not install over painted or coated surfaces that would prevent full metal-to-metal contact at the bearing points.
