The new HEA excavator defender window guard protects operators from flying debris that may be encountered while operating heavy machinery. The Defender Ballistic Series windows were designed by contractors who run heavy equipment and have been tested using ballistic standards. Our excavator window protection 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.

     Enhance the safety of your excavator with a UL752 Level 1 ballistic bolt-on excavator window guard better known as the Defender Ballistic Window. Regardless of if you are operating a hammer, auger, mower, mulcher, or a log processor you will feel safe knowing there is a 3/4” bullet-resistant door in place, to help protect your BIGGEST ASSET – YOU!

     The Defender Window not only adds extra protection to your excavator and you, but it is ideal for any job you will encounter. If you are reclaiming and deforestation, in steep areas like riverbanks, power lines, pipe lines, and railroad right of ways, or doing fuel reduction to prevent forest fires. Our Defender Ballistic Window and custom guarding is the protection you can count on!

     The ballistic front excavator window guards are designed with a unique fitment. They are bonded to a steel frame and are not milled and drilled out so that they are less susceptible to micro fractures.
