A reliable replacement set for your Spear & Jackson HG500B trimmer – three twin‑line spools that keep your garden looking sharp without the hassle of frequent refills.
Why choose this pack?
– Twin line design – two 5 m strands of bright blue cutting line per spool give you twice the cutting power and longer run time.
– Perfect fit – engineered for the HG500B model (and other Spear & Jackson strimmers), with a 65 mm outer width and 21 mm height that slides straight onto the cutter head.
– Easy installation – the spool’s inner diameters (12 mm base, 16 mm top) match the original design, so you can swap it in seconds, no tools required.
Key specifications
– Line width: 1.5 mm (ideal for medium‑thick grass and weeds)
– Line length: 2 × 5 m per spool (total 30 m of cutting line)
– Color: Blue, easy to spot on the ground
This set is a high‑quality aftermarket solution, compatible with Spear & Jackson trimmers but not an OEM part. It’s a cost‑effective way to keep your mower performing at its best, whether you’re tackling a small lawn or a larger garden plot.
