The Simpson APL4 Ornamental L Strap from Simpson Strong-Tie combines decorative style with genuine structural function, making it a practical choice for pergolas, decks, and other outdoor living structures. Designed for use with 4x or larger lumber members, it reinforces connections where one lumber piece intersects another at a 90 deg. angle, providing lateral strength at the joint. The ZMAX galvanized base coat beneath the black powder coat finish delivers extra corrosion resistance suited for exterior environments and pressure-treated wood applications. Part of the Outdoor Accents Mission Collection, this flat L strap brings a hint of Southwestern flair to any outdoor build without sacrificing structural integrity.

Key Features

• ZMAX galvanization with black powder coat finish - provides extra corrosion resistance for exterior and treated-wood applications, so the hardware holds up in demanding outdoor conditions without visible rust or deterioration
• Mission Collection aesthetic - adds a hint of Southwestern flair to outdoor living spaces, letting structural hardware double as a design element rather than something to hide
• 8-1/4 in. x 8-1/4 in. profile sized for 4x or larger lumber - covers the full connection point on common outdoor structural members, ensuring solid reinforcement with a clean, finished appearance
• 12-gauge steel construction - delivers the material thickness needed for lateral reinforcement at 90 deg. intersecting lumber connections without adding excessive bulk
• Compatible with Outdoor Accents structural screws and hex-head washers (sold separately) - installs with a coordinated hardware system designed to complement the ornamental finish, keeping the completed connection looking intentional and cohesive

Why This Product

• Form and function in one piece - unlike standard utility straps that get buried behind trim or paint, the APL4 is engineered to be seen, with a black powder coat finish and Mission Collection detailing that contribute to the overall look of a deck, pergola, or outdoor structure
• Built specifically for exterior exposure - the combination of ZMAX galvanization and black powder coating addresses the dual challenge of moisture and treated-lumber chemistry, making this strap a dependable choice where standard hardware would corrode prematurely
• A coordinated system rather than a single part - the APL4 is designed to install with matching Outdoor Accents hex-head washers and structural wood screws, so every visible fastener head ties into the same decorative finish rather than creating a mismatched look
• Straightforward fit for common structural lumber - compatibility with 4x or larger members means the APL4 works directly with the framing dimensions most often used in residential outdoor structures, reducing the guesswork in product selection
