The Simpson APA4 Ornamental 4x L Angle in Black Powder Coat is a 90 deg. angle connector from Simpson that bridges the gap between structural performance and decorative finish for outdoor framing projects. Designed for beam-to-post and rafter connections in outdoor living structures, this heavy-duty bracket makes corners stronger and cleaner-looking than angled nailing or screw fastening alone - all while adding the distinctive Southwestern character of the Mission Collection to your build.

Key Features

• Mission Collection Southwestern design - transforms a purely functional connector into a finished architectural detail, giving pergolas, shade structures, and outdoor frames a cohesive, intentional look
• Stronger than angled nailing or screw fastening alone - provides a more reliable structural connection at corners, reducing the risk of joint movement or failure over time in outdoor living and home repair projects
• Designed for nominal 4x lumber - engineered to fit standard 4x members precisely, ensuring a tight, consistent 90 deg. corner without shimming or guesswork
• Built from 12-gauge steel - delivers the rigidity and load capacity needed for structural beam and rafter connections without excessive bulk
• ZMAX galvanization with a black powder coat finish - layers two forms of corrosion protection for long-term performance in exterior environments and against the chemicals present in pressure-treated lumber
• Installs with Outdoor Accents structural screws and hex-head washers (sold separately) - pairing the bracket with matching fasteners completes the decorative look and keeps the connection fully coordinated within the Mission Collection system

Why This Product

• Form and function in one connector - most structural hardware is hidden on purpose; the APA4 is designed to be seen, letting the black powder-coat finish and Mission Collection styling become part of the finished look rather than something to conceal
• Dual-layer corrosion protection built for the outdoors - ZMAX galvanization combined with a black powder coat means this angle bracket is specifically engineered to hold up against exterior moisture and the corrosive compounds found in treated wood, not just adapted for it
• A stronger alternative to traditional fastening methods - relying on angled nailing or screws alone at beam and post connections leaves joints vulnerable; the APA4 creates a mechanically superior corner that holds its geometry over the life of the structure
• Part of a coordinated outdoor hardware system - the APA4 integrates with other Outdoor Accents Mission Collection components and matching fasteners, making it straightforward to achieve a consistent, professional finish across an entire outdoor framing project
