Flat white PVC bar for door bottom

[hurders]

I'm after a flat thin white PVC strip to finish the inside bottom of my front door. I can't seem to find any that are wide enough to cover the gap and still have enough overlap to be stuck to the bottom of the door.

Basically I'm after something like this - http://www.wickes.co.uk/invt/188234 but I need it to be about 50mm x 1m. Can't seem to find any with a 50mm width at the standard everyman DIY places, any suggestions?

youll have to buy a 60 or 65 and rip it down. Sadly they usually come in 5m lengths
