US size list · Canada page confirms head/SKU only

Husqvarna 122L string trimmer line size

Husqvarna lists the supplied T25 (L) head and states that the 122L T25 accommodates 0.065-inch, 0.080-inch, or 0.095-inch diameter line. Its page recommends 0.095-inch Titanium Force line for typical yard conditions.

This is a model-page specification, not a cross-brand rule. The T25 (L) listing is tied to the 122L. A replacement head, other 122-series model, or different SKU needs its own fit check.

Published T25 (L) line diameters

Line diameter	Metric conversion	Manufacturer note
0.065 in	about 1.65 mm	Accommodated by the cited 122L/T25 specification.
0.080 in	about 2.03 mm	Accommodated by the cited 122L/T25 specification.
0.095 in	about 2.41 mm	Accommodated; manufacturer FAQ says 0.095-in Titanium Force is recommended for typical yard conditions.

Regional and revision note

The 0.065 / 0.080 / 0.095-inch list above is transcribed from the US 122L FAQ. Husqvarna Canada confirms a T25 (L) head and the CA SKU 970 79 61-02 and lists a Canadian EN/FR manual, but its product page does not state the same line-size list. This page therefore does not assert those diameters for a Canadian 122L. Check the manual supplied with your exact unit and market.

Reloading the T25 head

Husqvarna’s model FAQ describes aligning the arrows, feeding replacement line through the eyelets so both sides are even, and twisting the bump knob to wind it. See the official page/video for the full instructions and safe setup; this text is not a substitute for the operator manual.
