Just had to buy a second set of Kanulocks on friday.
Just got my first 666 on friday and my green set ( 2.5m) of kanu's were 10cm to short


So had to but a yellow set (4m) so I could lock it up

Now have 2 sets and can't fault em.
I like em because you can have 1,2,3,4....... Boards all shapes and sizes and they always fit to good.
