Sometimes you buy trimmer line that comes with a cutter mounted on the package. They ether run their life on the package or fall off the day you get them home.
Simple bracket to mount the cutter on a surface. They seam to have not changed much over the years. One I have is new and the other over 5 years old.
Two to choose from. The only difference is the width. 20mm or 28mm wide.
Assembly:
Open the trimmer, place the lever through first and then the base should fit right in.
Support from the plate for the indent at the base.
