Easy install
Easy install but new head eats line very quickly. I liked the old style where you would wind the separate lines in yourself

Does this fit my product?Questions & Answers for Universal Trimmer Head Curved
Will this head fit the 2620T. I don't see the T in the list. And if the string jams inside the head, but only periodically, would replacing the entire head be our best bet?

for model number SRM-2620T
asked on 2023-05-24
Hello Susan, Thank you for your inquiry. We confirm that this part will fit your model, and would recommend replacing it if it is jamming. We hope this helps.
