Door Defender

Our Door Defender Protection System has a rugged outdoor-grade polyethylene construction featuring a patent pending bumper profile that acts as a spring to absorb door impacts. Door Defender is entirely waterproof and has been impact-tested to 3,000 cycles in conditions as harsh as -40 F and +130 F. The system includes a "one-size-fits-all" side post guard that stretches to cover nearly all auto rack structural elements and Holland's trusted nylon buttons with triple engaging lips.
