Product Description
As per Newport Website:
The MCC Mini Rail Channel Carrier attaches anywhere along the an MRL Series rail to quickly and securely tie down optical components. M4 clearance holes with 8-32 threads are provided. Spring-loaded hard polymer guides along the mating surfaces of the carriers ensure wobble free sliding motion and dependable linear alignment. By backing out the clamping screw, any carrier can be positioned along a rail without removing other components with a simple snap down motion. Then just tighten the screw fully for creep free clamp down. These one-piece aluminum carriers present a low profile and allow close spacing between components.
