A Higher Level of Protection


Step-up the safety on your skid steer with a UL752 Level 1 ballistic bolt-on door better known as the Defender BALLISTIC DOOR. Whether you are operating a hammer, auger, mower, mulcher, or a log processor you can feel secure in knowing there is a 3/4” bullet resistant door in place, to help protect your BIGGEST ASSET – YOU!

The Defender Ballistic Door is produced with a UL752 rated Level 1, ¾” polycarbonate. To receive this rating the polycarbonate must be able to withstand a ballistic attack from a 124 grain, 9mm FMJ lead core projectile with a 4” shot spacing from 15 feet.

The Defender Ballistic Door for skid steers has not been drilled out or milled down making it less susceptible to micro-fractures and is bonded to a steel frame making it flex less. Unlike most skid steer doors that might be rated for heavy impact, the Defender Door is rated to withstand a ballistic attack and is designed to install with your factory door components. No matter the industry your machines may be in its time to put real protection in place for you and your operators!

The Defender Ballistic Door for CAT skid steer installs easily onto the skid steer using factory hardware from your original door, including gasket, hinges, lock system and emergency escape system. HEA supplies a new windshield wiper and an adapter for the wiper motor.

Most polycarbonate protective structures on heavy equipment in the US market today, are only rated to withstand heavy impact. Most have been drilled or milled in order to install door handles, hinges, wiper blades and other fixtures. Drilling or milling the polycarbonate can weaken the polycarbonate by exposing it to micro fractures. Our doors are not drilled or milled. They are within a steel frame, customized to mount to a specific machine using factory mounting locations and factory hardware.

*Bullet resistant does not mean “bullet proof”, the Level 1 polycarbonate installed in the Defender Door 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).

PLEASE NOTE: This guard is intended as a brush guard only. It is not a certified FOPS/ROPS guard.
