The Simpson DTC 18-Gauge Roof Truss Clip is a galvanized steel angle connector from Simpson engineered to align roof trusses with nonbearing walls while accommodating controlled vertical movement under load. Originally designed for this specific framing challenge, the DTC has proven versatile across a wide variety of structural angle connections where consistent, straight corners and reliable load-handling performance are required. Its 18-gauge steel construction and G90 zinc galvanized finish deliver the durability and corrosion resistance that framing professionals expect on the job site, while a slotted leg design gives installers the adjustability needed for clean, efficient connections.

Key Features

• Slotted leg design allows for flexible installation and adjustability - lets installers fine-tune positioning during framing without being locked into a single fixed orientation, saving time and reducing rework.
• 1-11/16 in. slot permits vertical truss chord movement when loads are applied - relieves stress on nonbearing walls as the structure settles or live loads shift, helping protect the integrity of the surrounding framing.
• Made from 18-gauge steel - provides consistent strength across the connector body, giving the clip the rigidity needed for reliable structural angle connections in roof framing applications.
• Galvanized finish with G90 zinc coating provides extra corrosion resistance - protects the connector from moisture and environmental exposure, extending service life in typical residential and light commercial framing conditions.
• Install with 8d common nails - works with a standard fastener type readily available on any framing site, keeping installation straightforward and tool requirements simple.
• Not intended for floor applications - purpose-built for roof truss and nonbearing wall connections, so buyers can be confident the clip is properly rated and tested for the specific loading conditions where it will be used.

Why This Product

• Designed specifically for the roof truss-to-wall connection challenge - unlike a generic framing angle, the DTC was originally engineered to solve the precise problem of aligning roof trusses to nonbearing walls while allowing load-driven vertical movement, making it a purpose-fit solution rather than a workaround.
• The slotted leg prevents stress transfer to nonbearing walls - by permitting the truss chord to move vertically within the 1-11/16 in. slot as loads are applied, the clip actively protects nonbearing wall framing from forces it was never designed to carry.
• Versatile enough for a wide variety of structural angle applications - while purpose-designed for roof truss alignment, this connector handles light-duty framing joints and projects where a structural connection is needed, giving contractors a single connector that earns its place in the bag across multiple tasks.
• G90 galvanized steel construction built for long-term performance - the combination of 18-gauge steel and a zinc G90 galvanized finish means the clip resists corrosion and holds its structural integrity throughout the life of the roof assembly, without requiring special maintenance or replacement.

Frequently Asked Questions

What is the purpose of the slot in the DTC roof truss clip?

The slot in one leg allows for flexible installation and adjustability. Specifically, the 1-11/16 in. slot permits vertical truss chord movement when loads are applied, helping to prevent stress from transferring to nonbearing walls as the structure settles or loads change.

What fasteners should be used to install the DTC truss clip?

The DTC roof truss clip should be installed with 8d common nails. For best results, slot nails should be installed in the middle of the slot to allow the intended range of vertical movement.

Can the DTC truss clip be used in floor applications?

No. The DTC is not intended for floor applications due to the frequency of floor joist deflections and the potential for squeaks. It is designed for roof truss and nonbearing wall connections.

What corrosion protection does the DTC truss clip offer?

The DTC is finished with a Zinc Galvanized, G90 coating, which provides extra corrosion resistance, making it suitable for use in environments where moisture exposure is a concern during and after construction.

Note: Product not intended for floor applications due to the frequency of floor joist deflections and potential for squeaks.
