A network interface device includes a weatherable enclosure having injection molded, die cast, or stamped top and bottom cap portions and a body portion which is extruded. The injection molded portions are fabricated from a polymer, such as polyvinyl chloride, with a higher melt index than the grade of polymer used to fabricate the body portion. The body portion has top and bottom openings adapted to receive the top and bottom cap portions. The network interface electrical components are enclosed within the housing.

Why it's free to use
- Filed August 12, 1996 and granted July 25, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended August 12, 2016.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 12, 2018.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
