Use at your own risk.
Sierra did a very poor job installing a chain link and wood fence for me. They left chain link material all over in my yard and threw other pieces into the surrounding woods, installed one side of the fence at a cockeyed angle, built the wood gate so shabby that it wobbled and loosened all the nails holding it together withing a month, painted some of the hardware with a spray can in my back yard rather than using the coated material supplied by the fence manufacturer, installed the gate lock so low that the ground anchor couldn't be lifted to open the double gate, cut the wood along the bottom of the fence unevenly which is conspicuous since it is over cement, and just plain don't give a damn about the quality of work they do. DON"T USE THEM !!!
