High-Temperature Quick-Open Access Panels

With a ceramic fiber gasket and an iron frame, these panels withstand temperatures up to 2300° F. They’re commonly used in grease ducts and other high-temperature systems that need frequent cleaning. Panels clamp onto cutouts and the gasket keeps heat and material sealed inside. Use the included template to make the cutout. Also known as cleanouts.

Access Panels

Create an entry point for cleaning and inspecting duct. These panels cover cutouts and mount with screws. Also known as cleanouts.

Aluminum Panel and Frame—One-third the weight of steel, aluminum components are easier to handle during installation. They also resist rust in wet environments but won’t last as long as steel.
