Another new idea from Datamation Systems - the DS-OTK Tire Kit featuring super-soft rubber tires for laptop security carts (limited outdoor use for 16- and 24-module carts).

The kit includes: four 8" H x 2" W swiveling tires on nylon roller-bearing hubs with thread guards, 135 X 110 mm plate mount and two Max-Lok top-mounted brakes.
