SHIELDS 1/2 Inch Front Windshield for CAT Next Gen Excavators

CAT Next Gen excavators, models 316 through 395, use a curved front upper, glass 486-5450, and a curved lower, glass 491-7724. SHIELDS forms both in 1/2 inch polycarbonate to the original curves, duplicates the mounting holes and mills the edges so the factory hardware carries over, and coats both faces with SUPERCOAT so the wiper can keep running. You can order the upper and lower separately, in clear or tint. SHIELDS asks owners to confirm the glass numbers, so read them off your cab before you order.

SHIELDS 1/2 inch polycarbonate windows replace the curved front upper and lower glass on CAT Next Gen excavators, models 316 to 395. Both are curved like the original glass and coated on both sides with SHIELDS' SUPERCOAT hard coat. Each window is sold on its own in clear or tint.

SHIELDS CAT Next Gen Excavator Windshield Features: Excavator Glass Replacement for Models 316 to 395

• 1/2 inch formed polycarbonate, which SHIELDS rates at more than 260 times the strength of glass at half the weight
• SUPERCOAT hard coat on both sides resists abrasion, so you can keep using your wiper
• Upper replaces glass 486-5450; lower replaces 491-7724
• Curved upper and lower, formed to the shape of the original glass
• Drop-in replacement: mounting holes duplicated and edges milled so the original hardware carries over
• Tint is built into the material, not a film; SHIELDS advises against adding aftermarket tint film because the coating will not hold adhesives
