Safety

Adjustable travel, to eliminate finger-crushing hazards.
A pneumatic switch facilitates the clamping operation - eliminating the fatigue and inaccuracy of manual tightening.
A sensor on every fixture prevents the cycle from starting if a part is incorrectly clamped or positioned (for the electronic checking option, an LED identifies the vice which requires attention).
Jaw opening is unobstructed, since there is no space that can fill with chips.
If a parts works free from the jaws under the cutting force, machining is stopped immediately (to prevent damage to tools and wasted time).
The fixture can be carried easily via its two handles.
