The Simpson ABR105 Angle Bracket is a heavy-duty structural connector from Simpson engineered specifically for cross-laminated timber construction. Sized at 105x105x90x3, this angle bracket is purpose-built to create reliable, load-transferring connections between CLT wall panels and CLT floor panels or concrete slabs - making it a trusted component in modern mass timber structural assemblies.

Key Features

• Purpose-built for CLT construction - designed specifically for cross-laminated timber panel connections, so builders get a connector matched to the unique demands of mass timber assemblies rather than a generic workaround
• 11-gauge steel construction - delivers the structural strength and rigidity required for demanding panel-to-panel and panel-to-slab connections in load-bearing applications
• Zinc galvanized G90 coating - provides corrosion resistance suited to structural building environments, helping protect the bracket's integrity over the life of the assembly
• Versatile fastener and anchor compatibility - supports a wide variety of fastener and anchor options depending on required loads and application conditions, giving engineers and installers flexibility to meet project-specific performance requirements
• Supports multiple approved connection types - rated for CLT wall-to-floor, CLT wall-to-concrete slab, and broader mass timber structural assembly applications, reducing the need for multiple different connector types on a single project

Why This Product

• Engineered for the specific challenges of mass timber - unlike general-purpose angle brackets, the ABR105 is purpose-designed for cross-laminated timber construction, meaning its geometry and load-transfer characteristics align directly with how CLT panels behave structurally
• Handles two critical connection scenarios in one product - whether the application calls for CLT-to-CLT floor connections or CLT-to-concrete slab connections, the ABR105 is approved for both, simplifying procurement and specification across a project
• Durable finish for long-term structural performance - the G90 zinc galvanized coating is not just a surface treatment but a recognized standard for corrosion protection in structural connectors, supporting confidence in the bracket's lasting performance
• Adaptable load design through fastener flexibility - because a wide variety of fastener and anchor options are compatible, designers can dial in the connection performance to match actual project load requirements without being locked into a single hardware configuration
