The Simpson Outdoor Accents Avant Collection Deck Joist Tie by Simpson is a decorative structural connector built to attach 1-3/4-in. wide by 5-1/2-in. or taller joists to the side of nominal 4x or larger support posts in custom outdoor living structures and decks. Finished with ZMAX galvanization and a black powder coat, this connector delivers lasting corrosion resistance for exterior and treated-wood applications while keeping the look clean and intentional - making structural hardware a visible design element rather than something to hide.

Key Features

• Avant Collection design with straight edges and chamfered corners - gives your deck framing a clean, timeless appearance that complements modern and transitional outdoor builds
• Fits 1-3/4-in. joists paired with nominal 4x or larger support posts - matches common deck framing dimensions so the connector integrates naturally into your structure without modification
• Formed from 12-gauge steel - provides reliable structural performance at the joist-to-post connection where load transfer matters most
• ZMAX galvanization with a black powder coat - combines two layers of corrosion protection, making this connector suitable for exposed exterior conditions and contact with treated wood where standard finishes can break down over time
• Installs using Outdoor Accents structural wood screws and STN22 hex-head washers - the hex-head washer fastener system creates the appearance of a bolted connection, reinforcing the hardware-forward aesthetic of the Avant Collection

Why This Product

• Structural and decorative in one connector - rather than concealing your framing hardware, this deck joist tie is designed to be seen, bringing a refined, hardware-forward look to pergolas, decks, and other outdoor living structures without sacrificing the strength the connection requires
• Two-layer corrosion protection for long-term exterior performance - the combination of ZMAX galvanization and black powder coat is specifically engineered for outdoor and treated-wood environments, so the finish holds up where moisture and chemical exposure would degrade standard connectors
• Part of a coordinated hardware collection - the Avant Collection spans connectors and fasteners with a consistent design language, allowing builders and homeowners to carry the same straight-edge, chamfered-corner aesthetic across an entire outdoor structure
• Fastener system creates a finished, intentional look - installation with Outdoor Accents structural wood screws and hex-head washers produces the visual weight of a bolted connection, giving custom outdoor builds a crafted appearance that exposed standard fasteners cannot achieve
