New and improved Micro rail or focusing rail.
Same changes compare to previous version.
1) bottom rail thickness has been change from 1/2 to 5/8 inch and additional bars across has been added to increase strength of rail
2) Slider now has lock. After adjusting position you can lock down this position. No accidental movement any more.
Camera to subject distance can be adjusted in fine increments . Lead screw delivers 1.06 mm of travel per full revolution. Fast positioning can be done by pressing slider release lever and slide the slider on top of the rail. After seting position slider can be lock in position with side lock. Works very nice as a nodal slide.
Update
