Need help finding your model number?This bump knob is a genuine OEM replacement designed for string trimmer heads that use a bump-feed line advancement system, allowing additional cutting line to be released when the head is tapped on the ground. Molded from durable plastic in a distinctive red finish, it restores smooth, reliable line feeding and proper head operation when the original knob is cracked, worn, or no longer engaging correctly. Easy to install without special tools, it helps prevent line jams and interruptions, ensuring consistent trimming performance and efficient operation during regular use.
