Galvanized 5/8" steel buckles are the recommended product to be used with 5/8" Composite Cord Strapping. Our Galvanized Wire Buckles are coated with zinc to decrease rust and corrosion. Galvanized steel buckles will auto-lock and safely secure your load. Feed the composite cord strap through the buckle and after tensioning the load will auto lock creating a high efficiency seal. Your load strapped with composite cord may even be re-tensioned if it settles after strapping.
