✅ Exact OEM replacement at every thickness — including 3/8" and 1/2"
Every thickness is cut to exact OEM dimensions and drops into the factory opening. The perimeter is edge-milled to OEM glass thickness so the panel seats in the factory gasket and frame. Original latch, frame, and mounting hardware are reused — no drilling, shimming, or trimming; no hardware kit required.
Same impact-grade polycarbonate used in check-cashing and teller windows
260× stronger than glass at half the weight. Post-coated with SHIELDS® proprietary SUPERCOAT™ — a silicone hard coating applied after forming, abrasion-resistant to steel wool. Wiper-safe. Inspect wipers before use and clear debris from the frame seal. 10-year coverage against breakage, coating failure, hazing, and yellowing.
📋 Overview
A broken windshield stops the machine, exposes the operator, and typically means days waiting for a dealer part. The SHIELDS® SUPERCOATED™ Polycarbonate Windshield for Komatsu Excavator drops into the factory opening at every thickness — edge-milled at the perimeter — so it fits exactly as the OEM glass did. No modifications, no extra hardware. Year-round benefit beyond impact protection: polycarbonate reduces summer heat gain and winter heat loss, keeping operators more comfortable in all seasons, not just during forestry work.

🔧 Gasket Inspection
OEM gaskets are frequently damaged when the original glass breaks. Before installing, inspect the cab frame gasket — replace if torn, hardened, or deformed. A properly seated gasket is essential for weather sealing regardless of windshield material.
📦 Freight Damage — What to Do
eSkidSteer replaces items damaged in transit. Your obligation: inspect within 7 days of delivery and photograph any damage before filing a claim.
- Open the box immediately — freight damage to a flat polycarbonate panel is often invisible until unpacked. Do not sign a clean Bill of Lading without opening the box first.
- Inspect within 7 days of delivery. Damage reported after 7 days cannot be submitted.
- Photograph all damage — photos of the packaging and the panel are required to process the carrier claim.
- Contact eskidsteer.com at (866) 757-8337 with photos and we will arrange replacement.
⚠️ You must open the box before signing the delivery receipt. A clean signature = accepted delivery. Note any visible damage on the carrier receipt before signing.

❓ Frequently Asked Questions
Q: Will a thicker polycarbonate door still fit my OEM frame and latch?
A: Yes. Every thickness — including 3/8" and 1/2" — is cut to exact OEM dimensions and drops into the factory opening. The perimeter is edge-milled to OEM glass thickness so the panel seats in the factory gasket and frame. No accommodation is required for the added thickness.
Q: Does the 1/2" panel fit the same as the original glass?
A: Yes. The 1/2" panel is edge-milled to OEM glass thickness at the perimeter. It drops into the same factory frame, seats in the same gaskets, and is secured with the same hardware. No extra hardware, shimming, or drilling required.
Q: Can I still use my windshield wipers?
A: Yes. SUPERCOAT™ is wiper-compatible. Inspect your wiper blade before use and clear any rocks, sticks, or debris from the frame seal. Trapped debris scratches any surface — this is standard wiper maintenance, not a SHIELDS® limitation.
Q: What does the 10-year warranty cover?
A: Manufacturing defects: breakage, coating failure, excessive haze, and excessive yellowing — up to 10 years from date of sale. Does not cover scratching from normal use, impact damage from operation, or improper installation.
Q: Should I inspect or replace my gaskets?
A: Inspect them before installing. OEM gaskets are frequently damaged when the original glass breaks. Replace any gasket that is torn, hardened, or deformed before installing the new panel.
Q: What is SUPERCOAT™ and why does it matter?
A: SUPERCOAT™ is a proprietary silicone hard coating applied post-forming — not co-extruded into the material. Post-application gives higher adhesion and abrasion resistance. It is abrasion-resistant to steel wool and UV-stable. Cheap uncoated polycarbonate yellows and hazes within months outdoors; SUPERCOAT™ is designed to maintain clarity for the full warranty term.
