STIHL 0000 930 2342 RED LINE - 2.7mm / .105"

What It Is

This is an OEM STIHL replacement cutting line (part #0000 930 2342) for trimmer heads that accept a pre-wound RED LINE spool. The line is 2.7mm (.105") thick—a medium-duty diameter for clearing grass and light weeds on residential or semi-professional machines.

Fitment & Compatibility

• Brand/model: Designed for STIHL trimmers using the RED LINE spool system (e.g., AutoCut, SuperCut, or FixCut heads that specify RED LINE compatibility). Not universal—check your trimmer head’s spool type.
• Diameter: 2.7mm (.105"). Confirm your head accepts this thickness; too large may not feed, too small may break or not lock.
• OEM vs aftermarket: This is genuine STIHL, not a third-party replacement. OEM ensures exact fit and line quality, but costs more than generic spools.
• Deck size: Not applicable; this is for handheld trimmers, not mower decks.
• What to measure: Measure your old line diameter with calipers or check your trimmer’s manual for recommended line size. Also verify spool width (this spool is pre-wound, so it must physically fit the head cavity).

Key Things to Know

• Quality: OEM STIHL line is UV-resistant and less prone to drying/cracking than cheaper generic lines. It feeds smoothly in STIHL heads.
• Installation: Pre-wound spool—just drop it in, thread the line through the eyelets, and snap the head closed. No winding required. Takes under 2 minutes.
• Gotcha: This spool is not compatible with STIHL’s “TRI-CUT” or “FLIP-CUT” heads (those use different spools). Also, 2.7mm is thicker than standard 2.0mm or 2.4mm; it’s heavier and requires more engine power—best for trimmers with 25cc+ engines.
• Length: Spool holds about 18-20 feet of line, typical for a standard trimmer session.

Should You Buy It

Buy this if you have a STIHL trimmer with a RED LINE-compatible head and need a quick, no-hassle replacement with OEM reliability. It’s ideal for users who want consistent feed and durability without measuring or winding line. Skip it if you prefer aftermarket bulk line for cost savings, or if your trimmer uses a different head system.
