These are adjustable aluminum frames used to contain the flow of dental stone when making casts of footwear or tire impressions at the scene. Unique overlap clips allow eight inches or more of expansion. Each frame includes two “U” shaped bars, with two connector slides. Simply remove the connector slides when done, and the unit is a small, easily transportable item. Each frame can be used several times.
