Gator is the original case manufacturer to add built-in wheels and pull out handles to the rack mount case. Gator took the high quality construction and design of their deluxe 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! Available in: 4 Space, 6 Space, 8 Space, 10 Space* Note: Rackmounted equipment not included.
