This snow cone machine is great for the Party Rental Busisness.  The Sno-King is made with a heavy duty plastic case, (don't let this fool you it will take a beating and keep coming back).  I have seen first hand this unit pushed from a counter several times and still works. 

Sno-King snow cone machine with 1/3 HP motor, 1/4" thick polyethylene cabinet and lexan windows. Easy access to display area - no doors. The Sno-King is virtually indestructible under use in the most adverse circumstances or environment. The non-metallic construction will not "sweat" as much as other ice shavers. This Sno-King does not come with any accessories. For safe operation you must have one hand on the motor switch while the other hand pulls the pusher handle down to engage the spinning shaver head. Lightweight durable design is perfect for rental companies or people who travel with their snow cone machines. Dimensions 26" W x 14" D x 29" H. Electrical 120 Volts, 816 Watts, 6.8 Amps.
