BENEFITS OF HAVING GRADELOK

  • Reduced installation costs and taxpayer budget savings are an important consideration, however... Public utility directors, politicians and taxpayers should demand the specification of Gradelok for the public safety benefits!

  • The 18" distance is the most effective to enable a hydrant's traffic feature to break properly upon impact. If the traffic flange is buried or set too high, chances of it breaking correctly upon impact are greatly reduced.

  • The traffic flange is always exposed, easily-inspected for damage or leakage during routine maintenance.

  • Gradelok is manufactured of 350 Ductile Iron, cement-lined inside and tar-coated outside for corrosion protection, and conforms to AWWA C153/ANSI A21.53/AWWA C104/ANSI A21.4
