The Zacuto Z-Rail Slide Mount allows you to attach accessories to your Z-Rail. It features a threaded 15mm rod port on the side and offers a 1/4"-20 threaded hole on top for attaching articulating arms or other accessories. (There are also two 10/32" threaded holes on top for attaching a Z-Rail Cheese Stick and four M2 threaded holes for securing a Z-Rail Cold Shoe, but the Cheese Stick and Cold Shoe are no longer being manufactured by Zacuto.)

The threaded 15mm rod port can be tightened down on with a small screw that comes pre-installed on the side of the Slide Mount. An Allen key is included for this screw. You can also use two units to set up a dual rod setup. The Slide Mount can be adjusted along the length of the Z-Rail.
