Stens385-922 Trimmer Mate Fixed Line Trimmer Head, Replaces GB: GB21, 4-1/4 Outside Diameter, Should be Used with 0.13 Diameter Line,Silver

This is a simple aluminum disc with no moving parts. I drilled out the holes to use .155 line. Just thread 1 piece of line sixteen inches long through the holes and start whacking. I use Echo .155 line on a Honda 4 cycle 35cc brushcutter.

It is easy to install. It does take large diameter string and works well at holding that string. The only drawback is that replacing the string almost requires the use of pliers in order to do it relatively quickly.

No more plastic shredded line feed mechanisms in a self feeding line head. I can cut small woody stems and briars easily..Much of my terrain is hilly with numerous rocks. A stens head makes weed whacking quick and easy with the large diameter line that can be used with this trimmer head..

Item as described, heavy duty.

Would have given a 5 star but the washers didn't work with my sthil fs 250 and had to fabricate some. Also the holes will not readily accept 0.130 line as advertised but a quick trip with a drill bit clearance the unit to stellar performer. Simple and rugged! need a little more hardware...

Quality made, should last about forever. Works great, Saves line over the bump and go heads, has good balance and is very light weight.

Echo speed freak reccomend, but I never used the correct string size for this trimmer head and drilled new holes in different places for over sized string I used.

I appreciate that this head can take 0.13 trimmer line. But...the head is heavy. Given what I know now, I probably would not buy the head again.
