The Simpson HL37PC Heavy Ornamental L-Angle is a pre-finished structural connector from Simpson's Decorative Hardware line, engineered to connect timber members and reinforce right-angle connections in exposed wood applications. Fabricated from 7-gauge steel with a black powder-coat finish, this heavy angle delivers the structural performance required for timber framing while contributing a clean, ornamental appearance to any project where connectors remain visible. Compatible with Simpson structural hardware, it supports standardization and construction economy across heavy timber and architectural wood builds.

Key Features

• Connects timber and reinforces right-angle connections - provides a rigid L-shaped anchor at 90 deg. joints, keeping heavy timber members securely aligned under load
• Resists uplift and diagonal forces in wood connections - engineered to handle multi-directional stress, adding stability to exposed framing and timber structures
• Made from 7-gauge steel - heavy-duty material thickness delivers the strength needed for demanding timber construction applications
• Black powder-coat finish - a durable, pre-finished surface designed specifically for visible framing, eliminating the need for field painting and adding a refined ornamental look
• Part of Simpson's Decorative Hardware line - compatible with Simpson structural hardware, supporting consistent connector systems across a project

Why This Product

• Structural strength meets finished aesthetics - unlike plain galvanized angles that must be hidden or painted on-site, this connector arrives pre-finished in black powder coat, making it equally suited for structural duty and exposed architectural applications
• Purpose-built for heavy timber work - the 7-gauge steel construction and L-angle geometry directly address the connection and reinforcement demands of timber framing, where thinner connectors fall short
• Reduces on-site finishing labor - the pre-applied black powder-coat means no field painting or priming is required, saving time on projects where decorative exposed connectors are part of the design intent
• Promotes project-wide consistency - compatibility with Simpson structural hardware allows this ornamental angle to integrate seamlessly into broader connector systems, supporting standardization across heavy timber and architectural wood construction
