Tri-clone fast-feed string trimmer head TREX 1000 — accepts .060–.170, 2/4-string quick-load

The Tri-clone TREX 1000 is a fast-load bump-and-feed trimmer head designed to hold more line, accept heavy-duty diameters, and refill in under a minute without disassembly.

Upgrade your straight-shaft weed trimmer with a head built for faster reloads and stronger cutting performance. The TREX 1000 accepts line from 0.060" up to 0.170", lets you choose 2- or 4-string cutting configurations for added power, and uses a patented triangular eyelet plus a heavy-duty spring to deliver consistent line feed and longer bump-cap life. It ships with the parts you need to install on compatible gas or lithium battery straight-drive trimmers with an M10 x 1.00 mm thread.

How does the TREX 1000 make refilling faster and easier?

Reloading is simplified into three quick steps with no disassembly required. Align the spool cap arrows with the housing, feed line through the triangular eyelet to half length, then twist the cap clockwise until secure — the whole process takes approximately 35 seconds.

• No spring removal or messy rewinding required.
• Clear arrow indicators speed accurate alignment.
• Quick-load design reduces downtime and user frustration.

Which line sizes and cutting modes can I use for tougher jobs?

The head accepts a wide range of line diameters from thin trimming wire up to heavy-duty cord, letting you tailor cutting power to the task. You can load either two or four strands for wider, more aggressive cutting, and Tri-clone recommends Kodiak 0.155" or Wolverine 0.170" for heavy brush.

• Compatible line diameters: 0.060"–0.170" (multiple spool length examples listed).
• 2-string for normal lawns, 4-string for dense weeds and thicker brush.
• Recommended heavy-duty lines: Kodiak 0.155" and Wolverine 0.170".

What feeding and durability features keep the TREX 1000 reliable in the field?

The TREX 1000 uses a triangular eyelet and a robust bump cap that together stabilize line pattern and reduce wear. The heavy-duty spring gives controlled 2.5-inch line advancement per bump, and the bump cap is engineered to last over twice as long as standard designs.

• Triangular eyelet holds line pattern for even cutting results.
• Durable bump cap extends component lifespan.
• Heavy-duty spring ensures consistent feeding and fewer misfeeds.

Will the TREX 1000 fit my trimmer model and what’s included?

Install the TREX 1000 on straight drive shaft trimmers that rotate counter-clockwise and use an M10 x 1.00 mm threaded drive shaft with a flat gearbox. It is compatible with many models including Stihl straight-shaft machines; check your trimmer’s thread and rotation before purchase.

• Compatible: straight drive shaft, counter-clockwise operation, M10 x 1.00 mm thread, flat gearbox.
• Included in box: TREX 1000 head, spacer, and two rubber shims for proper fit.
• Not compatible with curved-shaft or different-threaded trimmers.

Who is this for: The Tri-clone TREX 1000 is ideal for homeowners and landscape pros who use straight-shaft gas or lithium trimmers and need faster reloads, greater line capacity, and options for heavier cutting. If you want to minimize downtime during yardwork, tackle thicker brush with confidence, and maintain a professional-looking edge and line pattern, this head gives a durable, easy-to-use upgrade. Confirm thread size and rotation before ordering to ensure compatibility.
