Open the CIPO recordAbstract From the Canadian patent
A switch or outlet box is formed with a substantially continuous channel around the front edges of the side walls of the box. The channel opens in the same direction as the box interior. A cover closes both the box and the channel, the cover having side walls which lie outwardly of the channel. The cover is dimensioned to loosely fit over the box so that gaps are formed to facilitate drainage of water from the channel. A latch structure holds the cover on. A hinged lid fits over a similar wall structure on the cover.

Why it's free to use
- Filed December 18, 1989 and granted July 22, 1997. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended December 18, 2009.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 18, 2011.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
