New genuine STIHL Chainsaw Bar Cover / Scabbard Guard with 4 3/4" wide opening. Part number, 0000 792 9175. This cover is typically used on larger saws with a WIDE 16"-18" bar. Generally fits MS261, MS271, MS291, MS311, MS362, MS391, MS461, MS462 with up to a 18 inch bar.

If you have a saw with a 16-18" bar and the bar measures about 2 3/4" wide, this is NOT the cover you need. While it will work, it won't fit tightly around the bar as it should. Measure the width of your bar, if it is about 2 3/4" see my other listings for the correct one. Stihl has a wide bar and a narrow bar that are both 16-18" depending on the saw you have. However, if your 16-18" bar measures around 4 3/4" wide this is the correct one.
