These PinHole Protectors™ are custom fit for your Demolition Man pinball machine.
 
This protector is for the plastic on the 3 bank top targets, this plastic is almost impossible not to brake one day.
Can be used under the plastic or even without them, it looks good just bare metal. 
Also many machines have this part missed during her hard life in exploration.
 
Made of 1mm brushed stainless steel.
