The Beckson Self Drain™ Opening Port is innovatively designed with an angled drainage ramp molded on the inside of the spigot. This design promotes drainage without having the hassle of making angled cuts in the hull. This also allows for thru-bolting, which is impossible in windows where an angled spigot extends below the bolt holes. The internal angle seats tightly against the gasket and lens, thus omitting an exterior water retention ledge present in most other ports. (No water-fall when you open the port after a rain.) Self Drain™ Opening Ports are ideal for mounting where installation is within 15° of vertical (with spigot length up to one inch). Longer spigots are available for vertical installations. For greater angles use Beckson Rain Drain™ Ports

The Beckson Rain Drain™ Opening Port is designed primarily for installation where cabin sides have excessive angles and other ports would collect rain and spray. These ports have all the features of Beckson's patented ports, with the addition of the patented Rain Drain™. The Rain Drain™ port, cut at 5/8", will drain while tipped up to 45° degrees. Unlike others, Beckson Rain Drain™ Ports have open drains which resist clogging and are easy to clean. Other drain windows retain up to one- third of a cup of water in each window when closed. Opening them can soak you and the boat. Where greater mounting angles exist, insist on Beckson Rain Drain™ ports for superior service.
