The new GATOR® 30-inch by 30-inch hopper car outlet gate significantly improves the unloading of grain, fertilizer, corn, and other dry and light commodities. The Stucki GATOR® outlet gate features ultra-high-molecular-weight polyethylene door seals for ease of operation, an automatic locking door plate mechanism, and a self-cleaning door wiper. A new security mechanism has been engineered to deter door-plate theft. This vital feature is the first of its kind in the rail industry.
