Tridon wiper refills are an easy fix for poor wiper performance. These wiper refills are available with metal rails or plastic backed for standard blades. The metal rail refills rely on quality natural rubber for their performance, while plastic back varieties use moly graphite infused rubber for excellent UV resistance. Both varieties are available in narrow, mid, or wide back sizes; and are designed to be trimmed to length where necessary. So selecting a refill to suit your vehicle is no trouble at all.
