The SHIELDS CAT C Series Polycarbonate Skid Steer Windshield is a formed replacement for CAT glass #258-4071 and OEM polycarbonate #380-9966. Designed for supported CAT C Series machines, it follows the curved factory windshield profile and is machined to match the original mounting points and hardware.
Available in 1/4″, 3/8″, and 1/2″ polycarbonate, with a 50% tint option in 1/2″, each windshield is coated on both sides with SUPERCOAT for abrasion resistance, UV protection, and continued windshield-wiper use. The 1/2″ version also includes the SHIELDS Seal gasket already installed.
What CAT glass does this windshield replace?
This windshield replaces CAT glass #258-4071.
Can this also replace the factory CAT polycarbonate windshield?
Yes. This SHIELDS windshield also replaces CAT OEM polycarbonate #380-9966.
Do I need to choose whether I am replacing glass or polycarbonate?
No. Both factory configurations use this SHIELDS replacement, so there is no separate glass or polycarbonate option to select.
How can I confirm this is the correct windshield for my CAT C Series machine?
Verify glass #258-4071 or OEM polycarbonate #380-9966 and compare the shape of your existing windshield with the product photos. SHIELDS notes that some C Series machines were built with the D-style windshield, so the model designation alone should not be used to confirm fitment.
What thicknesses are available?
Choose from 1/4″, 3/8″, or 1/2″ polycarbonate.
Is tint available?
Yes. Tint is available with the 1/2″ windshield.
How dark is the tint?
SHIELDS specifies the tinted polycarbonate at 50% light transmission.
Is the tint an applied film?
No. The tint is part of the polycarbonate material rather than an applied film.
What is the SHIELDS Seal?
The 1/2″ version comes with the SHIELDS gasket already installed while retaining the drop-in replacement design.
Do the 1/4″ and 3/8″ versions include the SHIELDS Seal?
No. The SHIELDS Seal is specifically used with the 1/2″ windshield.
Can I continue using my windshield wiper?
Yes. SUPERCOAT is applied to both sides for abrasion resistance during normal windshield-wiper use and cleaning.
Is there anything I should know about the 1/4″ windshield?
Yes. Because thinner polycarbonate has more flexibility, SHIELDS recommends adjusting the door latch toward the rear of the cab and keeping the upper gas strut as light as possible for the best fit when installing the 1/4″ version.
Is this windshield ballistic-rated or certified for operator protection?
No. This windshield does not carry a ballistic rating or a guarantee of bodily protection for a particular application.
Note: Compatibility depends on your CAT C Series machine using glass #258-4071 or OEM polycarbonate #380-9966. Always verify the existing windshield # and compare its shape with the product photos before ordering.
