The F016F04841 is the red spool cover for AFS 23-37 series brush cutter heads. An ABS plastic shell, round, with a snap rim around the edge and a side tab, two locating posts and a recessed center ring inside, and small arrow marks on the top. No tools needed: face it the same way as the old cover, align it with the base holes and press down until it seats. The cover protects the trimmer line and the feed mechanism from clippings and small stones, so the line does not snap and the base does not wear. Replace the whole cover when the snaps break and it will not close, the side tab cracks, or the posts wear and the cover wobbles. This cover is made for AFS 23-37 heads; for other similar cutters, compare the old cover size and snap hole positions, or send a photo to confirm.

 FAQ 

Q1: Does the F016F04841 cover come with the base?

The cover is one piece. The black base of the same head is a separate part, and the two hold the spool together. If only the cover is broken, the cover alone is enough; if the base is cracked too, both need replacing.

Q2: How do I fit the cover?

No tools. Put the two posts into the base, face the arrow marks the same way as the old cover, and press down along the snap direction until it clicks home.

Q3: Which trimmers does it fit?

It is made for AFS 23-37 series brush cutter heads. Other similar models are not guaranteed to fit, so compare the old cover or send a photo before ordering.
