Time to restock your trimmer line! This is a handy 3-pack of replacement spools designed for BLACK+DECKER trimmers that use the AF-100-3ZP line. Each spool has 30 feet of line with a 0.065-inch diameter—a common size for many electric and cordless trimmers. The brand is Gurdtopo, model AF-100-3ZP, and MPN is GH900. It comes with a 1-year manufacturer warranty. These are brand new, unused, and in their original packaging. No UPC. They're a direct fit for compatible BLACK+DECKER models, so you can swap out the old spool in minutes and get back to trimming your lawn or edging those walkways. The line is durable and should cut through grass and weeds nicely. Having a 3-pack means you've got backups ready to go when you run out mid-job. No more last-minute trips to the store! Whether you're a homeowner or a light-duty user, this affordable pack keeps your trimmer running smoothly all season long. Easy to load, easy to use.
