I would suggest doing a mod for this head. The mod can be found online and what it does is allows you to add a 3/8” bolt and washer to it to allow the plastic to last longer when bumping along sidewalks and concrete. The bolt acts as a metallic bump. The installation will fit mostly any model wmtrumner. I have a Milwaukee m18 and it mounted well. It holds a lot of line. I run .95 and it holds 30” and that’s a lot of line. The line goes in so easily it’s no hassle. The universal moi ting kid makes it easy. But if you get this perform the mod to add a bolt and washer to this head. You’ll get a lot more usage out od it before the plastic wear thin.
