Oregon Gatorline Round Weed Wacker/String Trimmer Line, .155 in. by 104 FT

What It Is

This is a 0.155-inch diameter, 104-foot spool of Oregon Gatorline round trimmer line, designed for gas and electric string trimmers (including EGO models) for heavy-duty residential weed whacking, edging, and clearing overgrown grass or light brush.

Fitment & Compatibility

• Diameter: 0.155 inch (4.0 mm) – fits most standard trimmer heads that accept line up to 0.155 inch. Check your trimmer’s manual for max line diameter; using thicker line can damage the head or motor.
• Length: 104 ft – enough for multiple reloads on most trimmers. Works with both bump-feed and fixed-line heads.
• Brand Fit: Compatible with EGO, Husqvarna, Stihl, Ryobi, and other brands using universal spools or pre-cut lengths. Not specific to EGO’s proprietary “Power Load” heads (those require pre-wound spools or specific diameter).
• OEM vs Aftermarket: Aftermarket replacement. No fit issues if your trimmer head accepts universal spools or you cut your own lengths. For EGO’s rapid-load heads, you may need to re-spool manually (see below).

Key Things to Know

• Durability: Gatorline uses a twisted, multi-sided design that cuts better than round line but can be slightly louder and less forgiving on hard surfaces (fences, rocks) – expect faster wear if hitting obstacles.
• Installation: Easy to re-spool onto most heads (bump-feed or fixed). For EGO’s Power Load system, you must remove the spool and wind manually – not as quick as their pre-wound spools, but doable with patience.
• Common Gotcha: The .155-inch diameter is on the thicker side for electric trimmers. If your EGO is a 56V model, confirm it’s rated for 0.155 inch; some lower-power models (e.g., older 15-inch) max out at 0.095 inch. Overloading can strain the motor.
• Value: $24 for 104 ft is competitive for a premium line. You get more footage than most single-spool packs, but check if you actually need heavy-duty line – if you only trim light grass, a thinner .080-inch line will be cheaper and easier on the trimmer.

Should You Buy It

Buy this if you have a gas or high-power electric trimmer (like EGO 56V) and routinely cut thick weeds or light brush, and you’re comfortable manually spooling onto your head. Skip it if you have a low-power electric trimmer, prefer pre-wound spools for convenience, or only trim lawn edges – a thinner, cheaper line will work better and save money.
