Abstract
A vapor plate for covering a manhole of a cargo transport tanker includes a plate member and one or more push rod assemblies. Each push rod assembly includes a guide tube extending through the plate member and a push rod extending through the guide member. A rod of the push rod moves linearly and rotationally within the guide tube. An adjustable collar of a resistance mechanism may be fixed to the rod so that the collar engages a spring allowing a user to generate a resistive clamping force by pushing downward on the push rod. A user may clamp the rim of a manhole between a lower handle of the push rod and the plate member with the resistive force by positioning the lower handle underneath the rim after generating the resistance force. The push rod assembly is sealed to prevent vapor leakage.
