JW Winco now offers steel and stainless steel indexing mechanisms. These components are designed to replace and simplify complicated indexing and safety mechanisms. The steel version has a black oxide finish knurled mechanism and is also offered with a black phenolic plastic handle for applications that may require frequent adjustments. The scale ring version has a matte chrome plated finish and the numbers and markings are in black. The stainless-steel version, only available with the knurled housing, has laser-engraved markings and is primarily designed for use in corrosion-free environments.
