Gator GRR4L 4U Polyethylene, 19" Roller Rack with wheels, pull-out handle

They took the high quality construction and design of their racks and strategically placed roller blade style wheels and a pull out handle. The best part is that the wheels do not interfere with the universal stack ability of these racks! The pull out handle has a locking mechanism to hold the handle firmly in place when in the extended position. Another example of Gator building user-friendly products at an affordable price!
