The Echelon line of residential decorative aluminum fence is best known for its outstanding strength, derived from a unique ForeRunner rail design. The ForeRunner rail allows this aluminum fence to follow changes in elevation while maintaining a secure distance under the fence. The Echelon rail also has an internal reinforcing web that allows the fence to take more abuse than conventional ornamental aluminum fences. Echelon is also an excellent choice for residential pools - thanks to our 9-stage aluminum powder coating process and limited lifetime warranty.
