Model LLDC

Lockdown Conversion Kit

The Lockdown Conversion Kit is developed to replace or convert a thief hatch to a Lockdown Hatch to meet environmental regulations. The Lockdown Hatch provides secure access to storage tanks without pressure or vacuum relief capability. When closed, it ensures a vapor tight seal that prevents leakage and evaporation loss. The locking mechanism allows for the use of a padlock or security seal. The Lockdown Conversion Kit can be mounted to existing thief hatch bases in service. Please contact the local representative or LaMOT Valve & Arrestor to verify if it is compatible to convert existing thief hatches in your application.
