A non-metallic masonry tie includes at least two longitudinal members of composite fibre. Composite fibre reinforcement extends between the two longitudinal members. The preferred composite fibre reinforcement is in the form of a bundle of composite fibres extending angularly between and wrapped around the two longitudinal members to form a symmetrical reinforcement pattern consisting of a plurality of triangles. This serves to equally distribute the forces acting upon the two longitudinal members.

Why it's free to use
- Filed November 7, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 7, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 7, 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.
