The sealed internal gear set and bearing assembly assures effortless movement, near zero lash, and a lifetime of maintenance free use in a commercial environment. The entire unit is computer machined from 3 aluminum billets leaving plastic used only for the dry-erase focus ring and interchangeable (.8 film pitch) drive gear.
A .5 pitch drive gear option is coming. The focus marking ring is designed for multi-angle viewing, and is indexed and attached magnetically. Our single rail mount design is rock-solid, incredibly versatile and opens up rail space for other accessories. The unit can be mounted left or right, at any height, with the focussing head angle adjustable to suit your needs.
