All About Ordering Beckson Newport™ Ports

  • CHOOSING BECKSON. Better design and construction than other manufacturers. NO CORROSION, NO CONDENSATION, NO LEAKS. NO WATERFALL when you open the window. Ready availability of component parts for the life of your port.
  • DETERMINING THE BEST SIZE. It is generally best to mount the largest port for the available mounting location for new installations. A larger port provides more light and better ventilation.
  • DETERMINING STYLE. The slope of the mounting location will indicate the type of port required, NEWPORT™ SELF DRAIN or NEWPORT™ RAIN DRAIN.
  • DETERMINING REQUIRED SPIGOT LENGTH. Estimate the hull or cabin wall thickness at each mounting location as accurately as possible. Cabin wall thickness determines required port spigot length. Both styles come in standard 1″ or 2″ spigot lengths.
  • FLEXIBILITY. Beckson Fixed and Opening Ports are engineered to standard mounting hole sizes for interchangeability and replacement of other manufacturer’s ports.
  • TECHNICAL ASSISTANCE. Beckson representatives are available during regular business hours to answer any and all questions regarding service or installation. Tel: 203-333-1412
  • INTERNATIONAL NOTE. All Beckson Opening Ports are CE approved.

VALUE All Beckson Opening Ports include screens and exterior trim rings.  All Beckson Fixed Ports include exterior trim rings.

Beckson Opening and Fixed Newport™ Size Chart

Using any of these dimensions will determine which Beckson Newport™ you have.  The overall dimension is the trim ring or frame size.  Please make sure to measure the length of the thru-hull portion with the lens closed to the edge of the trim ring.   That will tell you how long a spigot you need.  The spigot should be flush with the edge of the trim ring.  This will maximize the draining action of the frame.
