"Having introduced the world's first all-polyethylene rear trailer 'cone' as the replacement for 'cones' that have historically been fiberglass, we are pleased to advise that the new PolyCone produced by Granger Plastics Company is performing well in the field: Better impact resistance, better scuff resistance and lower cost. When a PolyCone is dented in the field, we just push it back into its original shape and send our enclosed car hauling equipment back on the road. Damage to fiberglass has always required bodywork to repair. We are pleased with the results of our material conversion project with GPC."
