Lehr Stacker Bars

Because every container deserves a perfect landing.

DURA TEMP designs and manufactures a full range of lehr stacker (loader) bars, pocket assemblies, and contact materials for the lehr furnace area. Our air-cooled tubular bar design, based on principles from the original U.S. Patent, provides built-in ventilation and structural rigidity—eliminating the need for forced-air cooling and reducing warping in high-temperature environments.

Each bar can be tailored to any OEM or custom loader system, ensuring a precise fit, consistent bottle positioning, and simplified maintenance.

Ventilated Design
