Trimmer Cord

Donuts

Pre Cut

Spools

Trimmer line (whipper snipper cord) in a range of thicknesses from 2.0mm to 3.9mm, sold pre-cut or on spools of various lengths and weights, from brands including Stens Silver Streak, Trail Blazer, Diamond Edge and Contractors Edge.

Thinner cord (around 1.5mm to 2.5mm) suits lighter electric or battery trimmers and edging work, while thicker cord (2.7mm to 4mm) handles dense grass and weeds on more powerful petrol trimmers. Check your trimmer's manual or spool housing for the recommended size, as using the wrong thickness can cause frequent breakages or strain the motor.

Frequently asked questions

Is thicker trimmer cord better?

Thicker cord cuts through dense grass and tough weeds better, but thinner cord is usually more efficient for light trimming around edges. Check your trimmer's recommended thickness before choosing.

How do I know what size trimmer line I need?

Lighter electric or battery trimmers typically use 1.5mm to 2.5mm line, while petrol trimmers can handle 2.7mm to 4mm. Your machine's manual or spool housing will usually state the recommended size.

What happens if I use the wrong size trimmer line?

Cord that's too thin breaks frequently and struggles with thick grass, while cord that's too thick can strain the trimmer's motor and cause overheating. Matching the line to your machine's specifications avoids both problems.
