Fixed Angle Plastic Corner Squares

ORC Forensics’ Footprint and Tire Track Frame of References are rulers and corner squares purposely designed to compliment the FBI’s Bureau Scales.  The original Bureau Scale is a specific corner square based on FBI guidelines and recommendations.  These items are used as official equipment for their photographers at crime scenes.  But don’t worry; we can sell them to you as well.  Use the Footprint and Tire Track Frame of References as measurement guides when taking photographs out in the field, the black-and-white graphics are calculated to give the user clarity and great readability from a distance.

These Corner Squares are the tools often used for measuring foot and handprints at crime scenes.  The 15cm x 30cm model holds the distinction of being the original Bureau Scale designed for the FBI several decades ago.  Many of the features on the rule are similar to our other Footprint and Tire Track Frame of References, including the .06 TK plastic it is made from.  Each of these Larger Corner Squares is double sided with inverse colors on the opposite sides.  Black Background/White Graphics & White Background/Black Graphics is the standard color option. Each of the Dual Edge Fixed Angle Corner Squares ordered comes with a ruler matching the graphics and length of the smaller side.

Another feature of our Footprint and Tire Track Frame of References are the Parralox Circles at each of the ends.  The Parralox Circles are a useful tool to the people who analyze the photographs that have our scales within the frame.  An investigator can examine the shape and displacement of the circle graphics in order to determine if the picture was taken at an angle or if there is a change of depth.  This is something that would be incredibly difficult to ascertain using rulers without these circles.  The Parralox Circles help to prove our commitment to making measuring devices that achieve the highest level of accuracy and functionality.
