Stronger Duct Connections with HDQC-XL Cleat

Article content provided by Duro Dyne.

Unlike traditional cleats that may struggle with size variation or material stress in high-pressure environments, the HDQC-XL Cleat is built to withstand the rigors of commercial and industrial HVAC systems. It locks securely into place thanks to strategically embossed “darts” that grip the flange and maintain pressure even under vibration or movement. By enhancing the contact between the duct flanges and the gasket, the HDQC-XL helps create a more reliable seal, which directly contributes to lower energy loss and improved airflow performance over time.

One of the most practical features of the HDQC-XL—and the entire Quad Cleat Plus family—is its universal compatibility. Whether you're working with multiple flange brands or various duct connection systems, this cleat fits virtually all commercial sizes.

This eliminates the need for contractors to stock different cleats for each flange type, streamlining inventory management and reducing installation delays. This saves time, cuts costs, and reduces risk, especially on large-scale or fast-paced jobs.

Constructed from durable 22-gauge, domestically sourced galvanized steel, the HDQC-XL is built for long-term performance in even the most demanding conditions. Other cleats in the series, including the QXCLT20-125 and DOMQCLT, offer variations in gauge and material, with customization options available for unique project needs.

Whether you're retrofitting an existing system or designing new ductwork from the ground up, the HDQC-XL Cleat delivers the strength, compatibility, and efficiency modern HVAC professionals depend on.
