A lay-in wireway includes channel members connected in an end-to-end configuration to form an enclosed rectangular channel. Covers hingedly connect to a flange extending from one side of the wireway. Hinges are then formed with the cover member and act as a stop to hold the cover member at an open position. Channel members connect with a hook and slot arrangement which slide relative toward one another at an end connector portion. Hooks and slots provide self alignment of connected channel members when slid into position.

Why it's free to use
- Filed January 30, 2001 and granted November 11, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 30, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 30, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
