CATERPILLAR 307 & 308 SERIES POLYCARBONATE EXCAVATOR DOOR | REPLACEMENT | #419-1289 | #419-9586

Upgrade your Caterpillar® 307 and 308 Series excavators with our precision-engineered polycarbonate windshield replacement panels. Available in ¼-inch, ⅜-inch and 1/2" thicknesses, these windshields provide superior operator protection and durability compared to OEM glass while maintaining excellent visibility for demanding job sites like forestry, mulching, brush clearing, mowing, and demolition.

Why Choose Polycarbonate Over Glass?

Our SSC® polycarbonate windshields are 250x stronger than glass and nearly half the weight, making them the ideal OEM replacement. Unlike glass, polycarbonate won’t crack or shatter, ensuring reliable protection in tough conditions.

• CNC-cut and formed to OEM dimensions

• Precision-milled edges and mounting holes for a direct fit

• Uses your existing factory hardware (no hardware included)

• SUPERCOAT™ protective coating applied to both sides for long-lasting scratch resistance

The result is an OEM-style windshield with the strength and performance needed for high-impact environments.
