Why is a Petzl PURline 65 meters?

 
 
 

The Petzl PURline, made for light hauling and as a rappel pull cord, comes in a rather odd length of 65 meters. Why is that, you might wonder?

I was curious about this, so I asked Petzl directly. 

When you rappel on your 60 meter climbing rope on the other side of a rope block, you’re using the PURline as a pull cord.

Your dynamic rappel rope will stretch about 5 meters, which takes you conveniently to the end of the 65 meter static PURline. Yes, those Petzl product designers are quite clever!

In case you're wondering, the Alpinesavvy graphic design department is hiring. I obviously need some help. =^)
