ClarkDietrich has received a third-party evaluation report for its series of rigid connectors. The report, IAPMO ER-731, certifies that the connectors meet defined performance standards and code requirements and enables their use on state-funded projects in California that require third-party validation.

“Third-party verification through IAPMO builds trust and reduces liability for specifiers, architects, engineers and building officials alike,” said Janine Dallies, category manager for ClarkDietrich. “This evaluation report includes blast design limit states, which is critical for Department of Defense projects and other high-security, high-performance building types.”

The evaluation report confirms compliance with the following building codes:

• 2024, 2021, and 2018 International Building Code (IBC)

• 2024, 2021, and 2018 International Residential Code (IRC)

• 2025 California Building Code (CBC), including Division of State Architect (DSA) and Department of Health Care Access and Information (HCAI) requirements

• 2025 California Residential Code (CRC)

• 2023 Florida Building Code—Building

• 2023 Florida Building Code—Residential

In addition to the evaluation report, ClarkDietrich will provide expanded design data supporting both blast and seismic applications. For these rigid connectors, available calculation methods include:

• Allowable Stress Design (ASD)

• Load and Resistance Factor Design (LRFD)

• Nominal Strength

The report covers multiple products in the company’s rigid connector portfolio, including Uni-Clip End Clip, Extended Uni-Clip, Extended Uni-Clip with Anchor Holes, SwiftClip (LA-, LE-, and LS-Series), EasyClip S-Series and E-Series and a Universal Strut Connector.

The Universal Strut Connector, coming soon, combines long-reach stand-off capability with a rigid, high-strength clip in a single, universal curtain-wall connection system designed for high-performance applications.
