105 Trimmer Line, 105 Weed Eater String, 105 String Trimmer Line, 105 Weed Eater Line, Commercial Round 105 Weed Wacker String- 0.105""-1038Ft-5Lb for String Trimmer Weed Trimmer, Orange

What It Is

This is a 0.105-inch diameter commercial-grade round trimmer line, sold in a 1,038-foot, 5-pound spool. It’s designed for heavy-duty trimming on gas-powered string trimmers that accept a 0.105-inch line, including many professional and semi-pro models from brands like Echo, Stihl, Husqvarna, and Ryobi.

Fitment & Compatibility

Before buying, check your trimmer’s manual or head for the maximum line diameter it can accept. This 0.105-inch line is thicker than standard residential lines (0.080–0.095 inch) and may not fit trimmers with small or fixed-line heads. It’s compatible with most bump-feed, speed-feed, and reload heads, but verify your head’s line capacity. This is an aftermarket product, not OEM, so it won’t have brand-specific packaging or pre-cut lengths. Measure your current line diameter with calipers to confirm—0.105 inch is about 2.7 mm.

Key Things to Know

• Quality & durability: Round line offers good all-purpose cutting but is less aggressive than star or serrated shapes. The commercial-grade material is more wear-resistant than standard line, lasting longer in heavy brush or along fences.
• Installation: Easy to load into most trimmer heads—no special tools needed. The 1,038-foot spool provides many reloads, so you won’t run out quickly.
• Gotcha: This line is too thick for many electric or battery-powered trimmers (most accept only 0.080–0.095 inch). Also, if your trimmer has a pre-set line length limiter, you may need to cut the line to fit.
• Compatibility check: If your trimmer head is marked for 0.095-inch line max, do not use this—it can overload the head and damage the trimmer.

Should You Buy It

Buy this if you own a gas trimmer that accepts 0.105-inch line and you do frequent, heavy-duty trimming—this spool is a solid value for pros or large properties. Skip it if your trimmer requires thinner line or if you only do light trimming; a smaller spool of 0.095-inch line will be easier to handle and cheaper.
