Plastic Angle Folding Corner Squares

ORC Forensics' Footprint and Tire Track Frame of References are rulers and corner squares designed to align with FBI's Bureau Scales. The original Bureau Scale, a specific corner square, is based on FBI guidelines. These tools are used by photographers at crime scenes, but we can also sell them to you. Use them as measurement guides when taking field photographs, with black-and-white graphics for clarity and readability. These corner squares are used to measure foot and handprints. The 15cm x 30cm model is the original Bureau Scale designed for the FBI. Many features, like the .06 TK plastic construction, are shared with other models. Each larger corner square is double-sided with inverse colors. A ruler matching the graphics and smaller side length is included. Our Footprint and Tire Track Frame of References also feature Parralox Circles at each end, aiding investigators in determining if a photograph was taken at an angle or if there's a change in depth. This demonstrates our commitment to accurate and functional measuring devices.
