Key Materials

Quality construction, built to last at sea.

  • The 190 Series Cast hatches are professionally assembled in-house with 316L, marine grade, stainless steel fasteners.  Stainless steel is ideal for harsh marine environments due to it’s rust & corrosion resistance, strength and luster.
