Abstract: A distance-transferring device comprising a plurality of interconnected rails. Each rail, when extended, is self-supporting. Once the rails are extended and locked in place between two points, two planes, or one point and one plane, an accurate representation of a distance between the two points, two planes or one point and one plane is obtained. This distance can be transferred to another location without having to memorize a numerical measurement. Opposing abutting angled ends provide for both easy access into corners and a clear visual for when the abutting angled end contacts a plane or mark. A rotating component allows for operating the invention in more than one plane. A movable catch hooks onto an object such as wood moldings to facilitate the measurement transfer without adding any error to the distance being transferred. Extension stops prevent the rails from longitudinal separation. Bubble vials are provided for leveling both horizontally and vertically.
