This RAM® Quick-Draw™ is designed specifically for the Zebra TC8000 and TC8300 scanners and consists of a double socket arm, a round 2.5" diameter round base with the universal AMPS hole pattern and a 4" clamp base. The clamp base will wrap around a maximum width of 4" and is tightened by screwing the two plates together with the included nuts and bolts. Rubber ball, socket technology dampens shock and vibration, as well as allows for almost infinite adjustment and perfect viewing angles.
