Ferco/G-U Reducing Sleeve – 7mm to 8mm (E-91440-01-0-FG)

This brass reducing sleeve provides a simple solution for spindle and handle compatibility issues. It allows you to convert a 7mm spindle to work with 8mm handle holes, or adapt an 8mm handle hole to accept a 7mm spindle.

Ferco multipoint locks originally used a 7mm spindle with matching 7mm handle holes. If you have handles designed for an 8mm spindle, this sleeve bridges the gap. Simply insert the sleeve into the mortise lock or handle to achieve proper fit.
