Key features

Compatibility for Flymo FLY021 & More - This spool is a direct replacement for the spool (OEM: 513937190), and works well with many common models. You don’t need to buy a new trimmer when the old spool wears out—just refill it with this replacement to save money., Premium Build for Tough Gardens - Made of high-quality ABS plastic and strong polyamide nylon cord, these spools are durable for long-term use.

The nylon line is flexible but tough enough to handle accidental hits on fences, walls and paving. It uses centrifugal force to reduce resistance, so it cuts more efficiently and gives a clean finish every time you use it., Enjoy continuous trimming - The string trimmer replacement spool is compatible with the Flymo Autofeed mechanism.

The spool automatically feeds out fresh line every time you stop and restart the trimmer, with the line cutter trimming it to the perfect length., Instant Tool-Free Replacement - You won’t have to deal with tangled wire or spend time hand-winding spools anymore. Each spool is pre-wound, so the winding is always neat and even.

To replace it, just take out the old spool and snap the new one in—no tools needed, and it only takes a few seconds., Pack of 4 - Comes with 4 durable replacement spools—You’ll always have a spare spool on hand when you need it, so you won’t have to stop working to reorder. It helps you keep your garden tidy all year round without frequent reorders..
