Stens Speed Feed 450 Trimmer Head for Straight-Shaft Trimmers — Heavy-Duty, No-Bump Quick-Feed (.080–.105" Line)

The Stens 385-288 Speed Feed 450 is a fast-feed replacement trimmer head that installs on most straight-shaft string trimmers and lets you quickly advance 0.080–0.105" line without disassembling the spool.

This heavy-duty replacement head is designed to save time on the job by combining a large-capacity spool with a bump-free feed system compatible with many commercial and homeowner straight-shaft trimmers. It replaces specific OEM parts and accepts multiple line diameters, making it a flexible option for users who want fewer interruptions while trimming tall grass, weeds, and turf edges.

How does the Speed Feed 450 make line changes faster?

The head uses a quick-feed design that allows the operator to advance line without taking the cover off the spool. Instead of manually winding or disassembling, you pull and lock line segments into place, so you get back to trimming faster.

• Spool holds approximately 20' of 0.095" line for long runtime between refills
• Compatible with .080", .095" and .105" diameters for flexibility
• No-bump or easy-advance operation reduces downtime
