The Stanley Fatmax Replacement Spool and Line 3-pack is designed for homeowners and gardeners using the Fatmax V20 string trimmer system who require consistent, high-quality cutting performance. The primary benefit of these 9-meter, 1.6mm nylon spools is their high resistance to impact and wear, which ensures longer intervals between replacements during intensive lawn maintenance; however, users should be aware that these are specifically engineered for the V20 series and may not be compatible with older or third-party trimmer models.

Each spool contains 9 meters of high-quality nylon line.
The line has a diameter of 1.6mm.
Yes, this spool is specifically designed to be compatible with model SFMCST933M1.
The package contains 3 replacement spools.
This line is optimized for grass and lawn edging. For heavy-duty brush, it may wear down faster than intended.
Check that the line is not tangled inside the spool housing and ensure the eyelet is free of debris.
Avoid direct contact with fence posts or thick wooden growth; ensure you are using the line speed appropriate for the grass density.
Clean grass clippings and dirt from the exterior housing clips; use a flat-head screwdriver if necessary to gently pry the tabs.
To install, ensure your Stanley Fatmax V20 trimmer is powered down and the battery is removed. Open the trimmer head housing, remove the empty spool, and insert the new line spool into the retaining slot, ensuring the line feeds correctly through the eyelet.
Compatibility: This product is specifically verified for the Stanley Fatmax V20 series and model SFMCST933M1.
Care: Store unused spools in a cool, dry environment away from direct sunlight, as excessive heat and UV exposure can degrade the elasticity of the nylon line over time.
