Models GE (English mic) and GM (Metric mic)

This type of UniSlide has a micrometer to measure travel to 0.001 inch or 0.01 mm. These models combine the Rapid Advance mechanism with a micrometer. The slider can be quickly positioned anywhere within the dovetail base. They are ideal for gauging position or travel when the zero reference point or home position must be movable. The micrometer range is 1 inch or 25 mm. Base length can be up to 30".

Feature Summary:
micrometer drive operation,
quick repositioning
movable zero reference point

GE and GM models are available in three Series (sizes): A15, A25 and A40.

Graduated Knob UniSlides

Another type UniSlide with the same resolution is the Graduated Knob UniSlide. They use a scale, graduated knob and accurate lead screw. Unlike the micrometer type above, this type can have a much longer travel distance, to 1 meter or more. Also, unlike the micrometer style, zero or home is fixed at one end of the slide. And, Graduated Knob UniSlides are available in all Series. Choose a Series. If you know your Series, you can Spec It for price and photo. Tell me more about Graduated Knob models.
