MERTS builds custom gates to fit your exact bin size. We use high quality steel to ensure your gate is durable and built to last. We proudly use Zerk grease fittings in the hinge pins to ensure the gate will function smoothly throughout years of repetitive operation. In the MERTS Double Clamshell Gate, the outboard ends of the hinge pins are supported to keep them in line as the parts wear. Heavy box and blades ensure your gate functions properly, and the blades are shaped to reduce friction. Our tooth gear quadrants are designed to give you years of trouble-free use.
