To order the correct Beckson Newport port, you need four things: the port size (model), the style (Self-Drain vs. Rain Drain), the required spigot length, and the mounting hole cut size. Beckson opening ports are engineered to standard mounting hole dimensions, so they interchange with and replace ports from other manufacturers, and all opening models ship with screens and exterior trim rings.
Beckson Newport ports at a glance
| Ordering factor | What to determine | Why it matters |
|---|---|---|
| Size (model) | Largest port the location allows (Size 310, 410, 414, 512, 714, 8RD) | Larger ports give more light and better ventilation |
| Style | Newport Self-Drain (sloped) or Newport Rain Drain | The slope of the mounting surface dictates the drain style |
| Spigot length | Standard 1 in or 2 in, based on cabin/hull wall thickness | Spigot must sit flush with the trim ring edge for proper drainage |
| Hole cut size | Match the model’s specified spigot/hole dimension | Standard hole sizes make Beckson a drop-in replacement |
Who is Beckson and why choose their ports?
Beckson Marine, Inc. has a 60-plus-year tradition of building high-quality, high-value marine equipment. Founded in 1955, the company is known for dependable, self-priming, all-plastic bilge pumps, and its product line also includes ports, deck plates, and hatches sold through a nationwide distributor network.
Beckson ports are designed for better construction than many competitors: no corrosion, no condensation, no leaks, and no “waterfall” of trapped water when you open the window. Component parts stay available for the life of the port, so a Beckson port can be maintained rather than replaced.
How do I determine the right size and style?
For new installations, it is generally best to mount the largest port the available location will accept, because a larger port delivers more light and better ventilation. The slope of the mounting surface then tells you which style to order: Newport Self-Drain for sloped locations or Newport Rain Drain otherwise.
Beckson Newport ports are offered in Size 310, 410, 414, 512, 714, and the round 8RD. Each model has its own hole-cut size, outside frame (overall) dimension, lens OD, and screen OD, so confirm the exact model before ordering.
How do I measure spigot length correctly?
Cabin wall thickness determines the required spigot length, and both Newport styles come in standard 1 in or 2 in spigot lengths. Estimate the hull or cabin wall thickness at each mounting location as accurately as possible before ordering.
To identify a port you already have, use its dimensions: the overall dimension is the trim ring or frame size. Measure the length of the thru-hull portion with the lens closed to the edge of the trim ring — that tells you how long a spigot you need. The spigot should sit flush with the edge of the trim ring to maximize the frame’s draining action.

Frequently asked questions
Are Beckson opening ports CE approved?
Yes. All Beckson opening ports are CE approved, which is useful to know for international and offshore installations.
What comes included with a Beckson port?
All Beckson opening ports include screens and exterior trim rings, and all Beckson fixed ports include exterior trim rings.
Can a Beckson port replace another brand’s port?
Yes. Beckson fixed and opening ports are engineered to standard mounting hole sizes for interchangeability, so they can replace many other manufacturers’ ports without recutting the opening.
What spigot lengths are available?
Both Newport styles come in standard 1 in or 2 in spigot lengths. Choose the length based on your cabin or hull wall thickness so the spigot sits flush with the trim ring edge.
What is the difference between Self-Drain and Rain Drain?
The choice depends on the slope of the mounting location: Newport Self-Drain suits sloped surfaces, while Newport Rain Drain is used for the other mounting orientation.
Why choose Beckson over other port brands?
Beckson ports are built to resist corrosion, condensation, and leaks, avoid the “waterfall” effect when opened, and keep replacement component parts available for the life of the port.
