25mm Rails & Carriers

MDR micro-dovetail rails are compact, low-profile rails that provide an in-line foundation and a three-dimensional building block for various component assemblies. The black anodized aluminum rails provide smooth carrier translation. Their precision dovetail construction allows components to be quickly attached, aligned, and rigidly held anywhere along the rails using RC rail carriers.
MDR micro-dovetail rails are available in lengths from 1.5 to 12 inches. The MDR-6.0i and MDR-12.0i ends are machined to be bolted together to make any rail length in 6-inch increments. MDR micro-dovetail rails may be secured at any angle on a microscope or laboratory table via counterbored clearance holes and slots.RC series rail carriers attach anywhere along MDR mini dovetail rails for quick and secure positioning of components. These one-piece aluminum RC rail carriers present a low profile, allowing close spacing between components. Spring-loaded, hard polymer guides along the mating surface of the RC rail carriers ensure wobble-free sliding motion and dependable linear alignment along the MDR micro-dovetail rails.
By backing out the clamping screw, any RC rail carrier can be positioned along the MDR micro-dovetail rail with a simple snap-on motion without removing the other carriers. Once in position, tighten the clamp screw fully for creep-free clamping. RC series rail carriers have attachments for either 8-32, 1/4-20, M4, or M6 mounting configurations. Notable variations in the line of RC rail carriers are the RC-20R and RC-8R. These simple but effective rail carriers allow the user to rotate the mounted device and lock it in place with one screw.
