Door frames, window frames, baseboards corner mouldings, etc. are trimmed , with solid wood e.g. oak, trim pieces (34). The trim pieces are fitted over splines (32) which are screwed to the wall. A jig enables the splines to be located accurately in position. The spline includes no beads, snaps or other features that would , require the oak trim section to flex; instead the trim is se-, cured by the friction arising from the fit of the spline into a groove (60) cut into the rear face of the trim section. In a variation a, pair of parallel grooves are provided together with a corresponding pair of splines, which are mounted on a web.

Why it's free to use
- Filed March 22, 1993 and granted October 22, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 22, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 22, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
