The 12 Nyloplast Ductile Iron Drop in Grate is the ideal grate choice for a variety of pipe types, including ADS Dual Wall N-12, SDR 35, and IPS/Schedule 40 pipe. The ductile iron grate is rated in areas with heavy foot traffic or light vehicular traffic (bikes, golf carts), where a sturdier, non-plastic grate is needed. Nyloplast ductile iron grates are a proven alternative to plastic drain grates and will not crack or break.
