The KP205LN and KP205RN presser feet are single toe feet designed for use on Durkopp Adler 204/205 class sewing machines and other machines with the same foot mount. Most people use a left toe foot to sew close to an edge, step, or buckle on the right (KP205RN). Less common are sewing tasks that require the right toe foot to sew close an edge, step, or buckle on the left (KP205LN). Check the pictures to make sure you order the correct one!
