Did you hear the news? Holland has won a Progressive Railroading Reader's Choice Award for the Door Defender™ Protection System!
Door Defender has a rugged outdoor-grade polyethylene construction featuring a patented bumper profile that acts as a spring to absorb door impacts. It includes a "one-size-fits-all" side post guard that stretches to cover nearly all structural elements of the auto rack rail car. Door Defender is also entirely waterproof with no adhesive required and features tear-resistant button slots. It's proved its performance and has been impact-tested to meet or exceed 10+ year field usage in conditions as harsh as -40° F and +130° F.
