3D printed from plastic Safety Interlock Switch Key for CNC machines. 
Fit most Mazak and Doosan and lot more machines. Please check dimensions from picture before make order.

This Key is only for setting or programming machine, I do not recommend working with door open and you take full responsibility for how you use it.

This key is made prom plastic, you have to remember not to hit it with door from the machine because you can break it in the locker.

If you require special color, leave message with order. Otherwise will send any color.
