Dewalt 90540850 Spool Kit for Trimmer

The Dewalt 90540850 Trimmer Spool Kit contains and retains the cutting line in trimmer head assemblies when in use. The spool is mounted in the trimmer housing, and it is filled with coiled line and, moves with the drive shaft so that the line is brought out to cut vegetation. This design ensures the controlled deployment and reining of the lines, and it equalizes centrifugal forces caused by the engine. It is installed along with the system of cutting and holds and directs the line through the head assembly. Its combination with the tool structure maintains steady cutting movement during regular trimming sessions.
