Bosch Strong spool Pro-tap' line To fit Bosch models (T)1.6mm

The line appears to be made of stronger material that was originally supplied so it looks as though it will last a lot longer. Also the spool provides enough line to provide three or four replacement windings, so although a more expensive product in the long term much better value for money.
Remember to wind it on the correct way though, otherwise it will unravel when you use the strimmer!

Bought this 3 weeks ago used to buy alternative but can't beat quality

Spool and reel different to your illustration. Hope it fits.
