Quintillus H09 Universal String Trimmer Head Kit with 12×11" .095" Triangle Lines — Tool-Free Install, Glass-Filled Nylon

Quintillus H09 is a universal string trimmer head kit that converts most gas and battery trimmers to a 360° rotating fixed-line system and includes twelve 11" .095" triangle trimmer lines.

This replacement trimmer head is engineered to work with a wide range of homeowner and professional brush cutters from major brands. The kit ships with multiple adapters so you can match the arbor on your machine, and twelve pre-cut triangle-profile lines for longer run time and cleaner cuts. Built from glass-filled nylon and 304 stainless hardware, the H09 prioritizes wear resistance and straightforward installation without tools.

Which trimmers will the H09 head fit?

The H09 is designed as a universal option and is compatible with many popular makes and models, provided you choose the correct adapter for your trimmer arbor. The listing covers brands such as EGO, ECHO, STIHL, Husqvarna, Ryobi, Greenworks and many more; always compare the adapter thread with your shaft before ordering.

• Includes adapter options for common thread sizes (M8, M10, 3/8-24, 5/16-24, 1/4-20, etc.).
• Compatible with both left- and right-rotating spindles.
• Works with gas and battery trimmers, brush cutters and multi-tools listed in the product compatibility details.

How do I install and load the trimmer head?

Installation is tool-free in most setups: swap the adapter that matches your arbor, screw the head onto the shaft, and it’s ready to use. Loading the supplied triangle lines is simple thanks to the rotating-cap fixed-line design that eliminates frequent unspooling and tangles.

• Choose the matching nut or bolt adapter included in the kit for your trimmer arbor.
• Screw the head on by hand; tighten per your trimmer’s user manual torque guidance.
• Feed the pre-cut 11" .095" triangle lines into the slots—no bumping or tangling required.

What performance can I expect from the triangle .095" line and head materials?

The included triangle-profile .095" line offers a balance of cutting edge and durability: it slices dense grass and light weeds efficiently while maintaining length for longer periods. The head’s glass-filled nylon body resists abrasion and impacts, and stainless steel fasteners reduce corrosion for extended service life outdoors.

• Triangle line size: 11" length, 0.095" diameter, 12 pieces included for convenient replacements.
• Head construction: glass-filled nylon for strength and wear resistance.
• Hardware: 304 stainless steel for corrosion resistance and reliability.

Is this trimmer head suitable for different ground and grass types?

The H09 kit is intended for general-purpose trimming across a variety of turf and terrain conditions. Its fixed-line rotating cap design keeps the cutting edge close to the ground for short, controlled trimming and is suitable for both soft and harder soil conditions where nylon line is appropriate.

• Good for edging, lawn cleanup and trimming shorter grass close to borders.
• Designed to resist line tangling and to work on uneven surfaces.
• Not intended to replace metal blades for heavy brush or thick woody stems.
