Wrong item
Part was good quality but not what I was expecting! When I ordered the bump cap I thought I was getting the piece that sits on top of the spool. This is the part you bump on the ground to advance the cutting cord. The part I recieved should be identified as the spool retaining cap. Feel like the nomenclature on the parts are very misleading. Especially when you do not provide a picture for the part.
