Simpson Angle Brackets (Model ABR, AE, E)

Built for CLT Strength and Stability

As cross-laminated timber (CLT) continues to rise in popularity for sustainable and large-scale building projects, reliable connection hardware becomes essential. Simpson Strong-Tie Angle Brackets are engineered specifically for CLT applications, providing the strength, durability, and flexibility required for secure panel-to-panel and panel-to-foundation connections. Made from heavy-gauge steel, these brackets are designed to withstand demanding loads while maintaining structural integrity over the life of the building.

ABR Angle Brackets

ABR brackets are versatile connectors designed to secure CLT wall panels to CLT floors or directly to concrete slabs. They’re built for high load capacity and cover all load directions, making them suitable for critical shear, uplift, and lateral-force applications. With the ABR255 model, anchoring to either CLT or concrete is possible, giving builders flexibility in their design and installation. Multiple fastener and anchor combinations can be selected depending on project requirements.

Key Benefits:

• Engineered for maximum versatility in CLT-to-floor or CLT-to-concrete connections
• Supports screws or nails with published load values
• Heavy-gauge steel construction ensures high strength and reliability

AE Angle Brackets

The AE series provides a straightforward solution for connecting CLT wall panels to CLT floors or concrete slabs. Like the ABR, the AE bracket is fabricated for strength but offers a slightly different configuration for specific installation needs. Contractors can count on it to perform under demanding load conditions while still being simple to install.

Key Benefits:

• Heavy-gauge steel design for dependable performance
• Ideal for CLT wall-to-floor or wall-to-slab connections
• Designed for efficient installation with compatible fasteners

E Angle Brackets

For projects that call for CLT-to-concrete anchoring, the E series angle brackets deliver dependable strength. A standout in this line, the E20/3 bracket is designed to handle installations where a gap of up to 2 inches exists between the CLT wall panel and the top of the concrete slab. This flexibility helps account for design tolerances or uneven conditions on the jobsite without sacrificing load capacity.

Key Benefits:

• Reliable performance for CLT-to-concrete connections
• Gap-tolerant design with E20/3 model supporting up to a 2" void
• Heavy-duty build rated for high loads in multiple directions

Why Choose Simpson Angle Brackets for CLT Projects?

Cross-laminated timber is transforming modern construction, and Simpson Strong-Tie provides the connection solutions to match. With ABR, AE, and E brackets, builders can confidently design and construct large-scale timber structures knowing their connections are tested, load-rated, and built for real-world conditions. Whether anchoring to concrete or tying walls to floors, these brackets ensure a strength that exceeds code compliance.

Common Applications

• Multi-story CLT buildings
• CLT wall-to-floor panel connections
• Wall-to-foundation anchoring in concrete
• Projects requiring tolerance for installation gaps
• Sustainable construction projects demanding precision hardware

Installation Considerations

• Always use Simpson Strong-Tie recommended fasteners for published load values
• Check project-specific load requirements before selecting bracket type
• For E20/3 installations, confirm the gap size between the wall and the slab is within 2" maximum allowance
• Consult Simpson’s technical documentation for complete design values and fastening schedules

Simpson Strong-Tie Angle Brackets (ABR, AE, E) are purpose-built for the demands of CLT construction. From high load capacity to gap-tolerant solutions, these brackets combine heavy-gauge strength with installation flexibility, ensuring every connection is as strong as the structure itself.
