Drain plugs are fitted with watertight seals
and some models have retaining legs to
prevent accidental loss. Plugs are available
separately as spares.
Inspection ports provide access to areas
under decks or behind bulkheads. Watertight
integrity is assured by threaded closure and
an O-ring seal.
PNP96, PNP97 and PNP390 are
manufactured with dissimilar materials
for the lid and deck ring to avoid binding.
PNP390 & PNP393 feature an
overlapping threaded lid for a smooth,
clean style.
Impact resistant, UV stabilised nylon.
