Sizing Information

To find what shield size you need, take down the diameter of the largest chuck you use on your machine. Multiply the diameter you measured by 1.5 and choose the shield size in A that is closest to your answer. Using this formula will guarantee that you will have room under the guard even though the jaws are open beyond the diameter of the chuck.

P/NA (diameter)B
TFM30011 3/4″ (300mm)9.5″ (240mm)
option 7″ (180mm)
TFM35013 3/4″ (350mm)
TFM40015 3/4″ (400mm)
TFM45017 3/4″ (450mm)
TFM50019 1/2″ (500mm)
TFM60023 1/2″ (600mm)

Example: A chuck diameter of 12″, multiplied by 1.5 gives you 18″. The closest measurement in column A is 17 3/4″ so we will therefore choose 17 3/4″ (450mm) in option “Screen Diameter A”.

Easy Installation

Why Have Safety Interlocking?

An electrical safety interlock prevents the machine from operating when the shield is opened.  This safety guard features an electric switch that disables the machine’s motor.  The switch is made in such a way as to prevents easy bypass of the interlock switch.

When we do on-site visits, we often see safety shields moved to the side and never put back on the machine.  An interlock is a simple solution to prevention of safety guard misuse or removal.
