UT20701 (D825SD) Homelite Trimmer - Parts

This is an OEM replacement part. It has a right hand thread screw to remove and attach it to the trimmer head. Its purpose is to hold the spool with the cutting line, in the spool housing. It also acts as the bumper to advance the line from the spool. This is a well used and abused part of the trimmer. It may be a good idea to order an extra one.
