The Simpson Outdoor Accents Sage System Middle-T Connector for 6x6 gives homeowners and DIYers a straightforward way to build strong, good-looking outdoor pergolas and shade structures without guesswork. Constructed from 12-gauge steel with a ZMAX galvanized base and a decorative black powder-coat finish, this connector brings together structural reliability and clean modern style in a single hardware kit. The middle-T design creates four-way 90 deg. angle connections, joining three beams to a post at mid-sections of a pergola frame to keep every corner consistent and square. The open-top design accommodates natural lumber size variances, speeds up installation, and supports a range of shade applications - from shade cloths to additional rafter configurations - while the included color-matched screws mean no predrilling and no extra hardware runs.

Key Features

• Four-way 90 deg. angle connection geometry - joins three beams to a post at pergola mid-sections with consistent, straight corners, so your structure stays square and aligned throughout the build.
• Open-top connector design - accommodates natural variances in lumber dimensions and simplifies placement during installation, reducing fit-up frustration and saving time on the job.
• Stop tabs built into the connector - create a defined end point for each post so beams seat correctly and cannot drift out of position during or after assembly.
• ZMAX galvanized steel construction with black powder-coat finish - delivers heavy-duty corrosion resistance for lasting outdoor durability while keeping the hardware visually refined against wood framing.
• Includes 45 color-matched SD10112DBB Outdoor Accents connector screws - no predrilling required, so the connector goes up quickly right out of the box without any additional fastener purchases.
• Modular Sage System compatibility - the clean, open design works with accessories such as shade cloths or additional rafters, letting you customize and expand your pergola or shade structure over time.
• 12-gauge steel construction - provides the structural strength needed for outdoor beam-to-post connections while keeping the connector profile sleek and unobtrusive.

Why This Product

• Built for DIY success without sacrificing structural integrity - the open-top design, stop tabs, and no-predrill screw installation remove the common pain points of pergola framing, making it practical for homeowners to achieve contractor-quality results with 6x6 lumber.
• Corrosion-resistant hardware that holds up in outdoor conditions - the combination of ZMAX galvanized steel and a black powder-coat finish means this connector is built to resist weathering over years of outdoor exposure, not just at installation.
• Everything needed for the connection is in the kit - the 45 included SD10112DBB color-matched screws eliminate the need to source separate fasteners, keeping the finished look consistent and the project on schedule.
• A connector that grows with your project - the modular, clean design integrates with shade cloths, additional rafters, and other Outdoor Accents Sage System accessories, so the structure can be adapted or expanded without replacing the core hardware.
