Looking to create a trench drain system with these grates? We have a variety of rails/frames to make the build easier.
NOTE: Due to the weight of this product, expect higher than normal shipping costs. Contact Customer service to explore possible alternatives (ground vs. freight). All raw cast iron grates begin to naturally rust with exposure to any form of moisture and will appear bright orange before settling to brown.
