The Killer Tools Ultimate Digital Tram, No. ART90MX, is designed to easily deliver laser accuracy from 1.2" (30mm) to 94" (2,387mm) with an SAE and metric digital readout. Aluminum telescoping sections with cam locks improve handling and reduce sag, and the adjustable laser tray enables measurements anywhere along the tram with no fixed zero-point. The set includes two nylon storage bags, a shortening attachment, two 5" pointers, and two 12" pointers.
