TFAL / AP45 Framing Anchors — Versatile Shear Transfer for Single and Double Top Plate Framing
The TFAL and AP45 framing anchors are 18-gauge galvanized steel connectors designed to transfer shear force from the top plate to blocking or rim joist connections in wood-frame construction. Engineered for both single and double top plate situations, these anchors feature an improved nail pattern that helps prevent splitting of wood members during installation. Built for contractors and framing professionals, they are ICC-listed under ESR-2556 and available in G-185 Triple Zinc or Hot-Dip Galvanized finishes for corrosion resistance in demanding environments. Bending slots are incorporated into the design to allow accurate field bends for 2-way and 3-way anchoring tie configurations on the job.

The TFAL and AP45 stand out from standard framing hardware by offering built-in bending slots that enable accurate 2-way and 3-way field bends without additional tools or custom fabrication. The TFAL provides load capacity up to 910 lbs at C=1.6, while both models share the same fastener schedule, simplifying procurement and installation on the job site. ICC listing under ESR-2556 provides the code compliance documentation contractors need for inspections.
Key Features & Benefits
Shear Force Transfer
These anchors are specifically designed to transfer shear force from the top plate to the blocking or rim joist connection. This is a critical structural function in wood-frame construction, ensuring lateral loads are properly distributed through the framing assembly.
Improved Nail Pattern
The improved nail pattern is engineered to help prevent splitting of wood members during fastening. This reduces callbacks and material waste, particularly important when working with engineered lumber or tight-grain dimensional lumber.
Bending Slots for Multi-Way Anchoring
Integrated bending slots allow the installer to make accurate field bends for 2-way and 3-way anchoring tie configurations directly on the job. This versatility eliminates the need to stock multiple specialized connectors for different framing conditions.
Single and Double Top Plate Compatibility
Both the TFAL and AP45 are designed to work in single and double top plate situations, making them suitable across a wide range of residential and light commercial framing layouts without requiring separate hardware for each condition.
Corrosion-Resistant Finish Options
Available in G-185 Triple Zinc or Hot-Dip Galvanized finishes, these anchors are suited for applications where moisture exposure or treated lumber contact is a concern. Contractors should call for availability of specific finish options.
ICC-Listed (ESR-2556)
Listing under ICC ESR-2556 provides third-party code compliance documentation, supporting permit applications and inspections on projects where engineered connector approvals are required.
Common Applications
Top Plate to Rim Joist Connection
Transfers shear loads from the top plate down to the rim joist, a standard requirement in platform-frame construction for lateral load resistance.
Top Plate to Blocking Connection
Anchors blocking members within the floor or wall assembly to the top plate, maintaining structural continuity where rim joist installation is not practical.
Single Top Plate Framing
Provides the required shear connection in single top plate wall systems, accommodating the reduced plate depth without compromising load transfer.
Double Top Plate Framing
Equally suited for double top plate configurations, giving framers a single connector solution across both common plate conditions on the same project.
2-Way and 3-Way Anchoring Ties
The bending slots allow the anchor to be field-bent into 2-way or 3-way configurations, making it useful at corners, intersecting walls, and other complex framing junctions.
