Inspection plates provide easy access to tanks and
compartments for inspection, cleaning and maintenance, or to shutoff valves.
Plastimo’s screw-out type inspection plates have a unique self-aligning center
with self-cleaning buttress threads instead of crossthreads so they won’t jam
and they screw on in a single start. The self-cleaning threads prevent salt or
sand clogs, too.
ABS or Polypropylene?
ABS plates have a finer finish and a sharper look than polypropylene plates, and
should not be exposed to harsh chemicals, so they are generally used for
interior installations. ABS plates include an O-ring for watertight
installations. They should be washed with soapy water only. Polypropylene plates
are relatively soft and pliable, so they don’t require a waterproof seal.
Polypropylene can accept most solvents found in marine cleaners, which is why
they are preferred for deck, cockpit and other exposed installations.
