Key Features of this Template:

• Multi-Backset Support: Markings for 60mm, 89mm, and 127mm included.

• Handing Guide: Instructions for switching the latch bolt handing before you slide it in the door.

Note for the boys on site: When you print this, make sure your PDF settings are on "Actual Size". Use a ruler to double-check the scale bar on the page before you start drilling into an expensive fire door!
