The next time you are wondering how to transfer matching holes from one part to another and there seems no obvious way to do it - look to the strap duplicator.

This tool has been around for awhile - but some builders may not be familiar with it. When there is a hole underneath the material that needs a new hole drilled, this simple but ingenious tool provides the means to locate the exact location for drilling. It is one of those tools that you forget about until you really need it! The more often you replace or rebuild parts on an existing structure (like when you damage a part while building) the more you will make use of this tool. 

Watch a quick demonstration and file the idea for future use!
