Simpson Strong Tie APA21 90 Degree Black Steel Angle

Product Description

The SIMPSON STRONG TIE APA21 is a 90-degree structural angle connector fabricated from galvanized steel with a black powder coat finish. It is designed to provide rigid corner connections that exceed the load capacity of traditional nailing or screw-only fastening methods. The black powder coat layer adds corrosion resistance, making this connector suitable for outdoor environments where moisture and weather exposure are constant concerns. Licensed contractors, framers, and deck builders install this connector where code-compliant, high-strength framing connections are required at right-angle joints.

This angle connector is intended for outdoor structural applications including deck framing, pergolas, garden structures, and similar wood-frame assemblies. It is specifically rated for use with treated lumber, which can accelerate corrosion in connectors lacking adequate protective coating. The black finish also provides a finished aesthetic suited to exposed architectural framing where connector appearance is a design consideration. Compatible Outdoor Accents Connector Screws are sold separately and recommended for use with this connector.

Key Features

• 90-degree angle geometry for rigid right-angle framing connections
• Galvanized steel base with black powder coat finish for corrosion resistance
• Rated for use with treated wood lumber
• Exceeds load performance of nailing and standard screw fastening alone
• Finish suits exposed framing in decorative outdoor structures

Compatibility

Designed as an OEM-style structural angle connector for outdoor wood-frame construction applications including deck framing and garden structures. Compatible Outdoor Accents Connector Screws are sold separately.

Installation Notes

Installation is performed by licensed contractors or qualified framers following applicable building codes. Power down any adjacent electrical runs and clear the work area before beginning structural fastening work. Use only manufacturer-recommended fasteners, such as compatible Outdoor Accents Connector Screws, to maintain rated load values. Do not substitute standard drywall or deck screws, as they may compromise the connection strength.
