Frequently Asked Questions

Q: How do I know if these replacement spools are compatible with my Parkside grass trimmer?

A: These spools are designed to fit a broad range of Parkside PRTA 20-Li and PRT series trimmers. Check your trimmer's model number and IAN code (usually found on the label near the battery compartment) and compare it against the compatibility list above. If your model is listed, these spools will fit.

Q: What is the line diameter and length included on each spool?

A: Each spool comes pre-wound with 2 × 4 metres of 1.6mm diameter spiral-design nylon copolymer resin cutting line — ideal for fast, clean trimming of grass and light vegetation.

Q: Is installation difficult? Do I need any special tools?

A: Not at all! These spools are designed for easy, tool-free installation. Simply remove your old spool, align the new one with the trimmer head, and click it into place. The auto-feed mechanism takes care of the rest, so you can get trimming right away.

Q: Why should I choose a 6-pack instead of a single spool?

A: The 6-pack is a great value option for regular gardeners or those who use their trimmer frequently. Having spare spools on hand means you're never caught off guard mid-trim — simply swap in a fresh spool and keep going without any delays.
