Big Horn 70139 Latch Mortiser for Bore Master, 1 Inch x 2-1/4 Inch

This design offers a removable steel blade that you can sharpen with your own file but also replace with a new blade when needed. Easy to use, just insert the aluminum center alignment plug into the 1" latch bore on the edge of your door, then strike the steel handle with your hammer to create the outline of the 1" x 2-1/4" latch that you are installing. Use your own hand chisel to finish the mortise in the door edge. Replaces Templaco LM-001.
