A pawl assembly is disclosed comprising a threaded shaft of noncircular cross section, a pawl of generally elongate shape having a circular through hole and a clip, that is nonrotatably mounted on the shaft and which contacts the pawl to prevent rotation thereof. The clip has a noncircular through hole that corresponds to the noncircular cross section of the shaft and a bent portion that contacts a side surface of the pawl to prevent rotation. By using such a clip, the pawl can be oriented in multiple angular directions while also providing for precise axial placement on the shaft. The pawl assemblies may be used in latches for cabinets and the like.

Why it's free to use
- Filed April 14, 1993 and granted April 28, 1998. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 14, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 14, 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.
