Our Defender Ballistic Series windows were designed by contractors who run heavy equipment and have been tested using ballistic standards. Our Caterpillar excavator window protection glass is a UL752 rated, level 1 ballistic polycarbonate window. Unlike the OEM window that already comes installed, ours can withstand a ballistic attack. The Defender Ballistic Series is mounted to the machine using the factory locations on the front of the cab.

What Makes Our Ballistic Windows Different?

    Our Caterpillar ballistic defender window glass has not been drilled or milled therefore making it less susceptible to micro-fractures and is bonded to a steel frame making it flex less. Unlike most excavator windows that might be rated for heavy impact, the Defender Window is rated to withstand a ballistic attack. Our excavator windshield guards have been designed to install with your factory window components. No matter the industry your machine may be in, it's time to put real protection in place for you and your operators!

*Bullet resistant does not mean “bullet proof”, the Level 1 polycarbonate installed in the Defender Ballistic Window is rated to withstand a ballistic attack from a 124 grain, 9mm FMJ lead core projectile from 15 feet with a shot spacing of 4 inches. This test is performed in a controlled environment at varying temperatures as low as -26 F and as high as 120 F (outside temperature).
