Open the CIPO recordAbstract From the Canadian patent
The present invention is directed to an improved tool for use in mounting a joist hanger on a header. The tool can be made to accommodate a joist hanger of a single size or can be made so as to be adjusted in size to accommodate joist hangers of different sizes. In the latter cases, a first set of bars can separate from the adjacent, second set of bars to expand the width of the space at the side of which a number of magnets are carried. This allows for greater versatility than when the bars are stationary.

Why it's free to use
- Filed May 12, 1994. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended May 12, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 12, 2016.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
