String head housing.
The description clearly states that it is for a Homelite trimmer. Even confirmed it with a representative from Replace Parts. The part did not match. Tossed it in the trash can because it was not worth returning it. Very disappointed with this transaction. Never again.

Does this fit my product?Questions & Answers for String Head Housing
Are parts still available for this Homelite model (UT33600A)? I'm looking for the string head housing that attaches directly to the trimmer shaft. It has a hexagon hole that is inserted onto the shaft and tightened with a nut.

The bottom of my bump head was worn down to nothing and I couldn't get it to come off. I'm not sure whether I continued to tighten it when I tried to remove it, but on a straight shaft (not curved) trimmer, you have to loosen clockwise, so once I finally took it off I separated the housing from the main spindle, which wasn't damaged.
I simply replaced with a whole new replacement housing and string attachment and counter clockwise tightened it on. Works like a charm.
