When mounted on a rail, a stage's translation axis is perpendicular to the adjustment axis of the rail.


  • Outer Dovetail Compatible with 2" XRN Quick Connect Stages
  • Allows for Coarse Adjustment of Mounted Components
  • 150 mm, 250 mm, and 500 mm Lengths Available
  • Counterbored 1/4" (M6) Mounting Slots Compatible with Imperial and Metric Breadboards
  • Additional Dovetail Compatible with 34 mm Rail Accessories

These 2" rails provide a convenient way to mount our XRN series stages and accessories on a breadboard or optical table. All rails feature an outer 2" male dovetail for mounting components with matching female dovetails as well as an inner 34 mm male dovetail for mounting other clamps and platforms.

A mounted component can be translated across the entire length of the rail. The XRN25DR2, XRN25DR, and XRN25DR3 come in lengths of 150 mm, 250 mm, and 500 mm, respectively. Rails with custom lengths up to 750 mm can be custom ordered by contacting Tech Support. For XRN25 stages, travel along the rail would be in the direction orthogonal to the stage's translation axis. The graduated scale engraved along one edge of each rail makes it easy to repeat adjustments between multiple locations on the rail; XRN25-RC3 rail carriers can be used to mark a specific location on the rail before moving the stage.

The rails feature 1" long, 1/4" (M6) counterbored mounting slots and a central 1/4" (M6) counterbored mounting hole that allow the rail to be used with both imperial and metric breadboard hole patterns. Standard cap screws can be used with these rails without interrupting the translation of mounted components.
