Hitachi EX300-2 Left Door Glass Frame Assembly

This left door glass frame is engineered as a direct replacement for Hitachi EX300 series hydraulic excavators including EX300-2, EX300-3, and EX300-5 models. The component constitutes the structural metal framework surrounding the operator cab left door window opening, supplied without the glass pane. It is designed to restore cab structural integrity and weather sealing capability. Fabricated from high-strength steel with corrosion-resistant primer finish, the frame features OEM-equivalent bolt-hole patterns and mounting geometry for precise fitment. Compatible with Hitachi EX300LC long-carriage variants. Aftermarket cross-references include NSYCH156302, WYEX300-2, 737417878617, and 737417878624. Glass, seals, and mounting hardware are not included and must be sourced separately.
