It makes sense to carry a tow rope in the car, but even more so in winter.
This Maypole 3 tonne tow rope starts at 1.8m and stretches to 3.8m, eliminating snatching. Its drop forged hooks make it quick, clean and easy to use - there's no need to grovel around under the car looking for places to tie on or loop through. Just clip it into your towing eye, front or back. It's basically a big bungee cord, covered in a strong, multi-coloured sleeve.
We use them in all our vehicles here, mostly for pulling pallets out of vans, but have never found anything better at trade shows here or abroad.
