Jamb mortising template. Four of the most popular templates for residential locksets are combined onto a single carrier. This template will produce four finish strike mortise sizes for the most popular residential locksets. It uses a 1/2" cutter and a 5/8" outside diameter router template. Using a double bearing setup with this template will increase the contact area on the template and reduce the chance for template flex. No need to remove the door stop when using this template. Template is designed to place the back edge of the strike plate as close as 3/16" from the door stop or it can be adjusted to a wider setting using the built in stops on the underside of the template.
