^^^ Nar that just reinforces what I thought - it has a lot of holes so it is not infinitely adjustable.
There will often be a slighty too tight position and slightly too loose position
Might be fine travelling for short distances but I can see that if it is the tiniest bit loose the board can move up and down... even a couple of mm. At highway speeds in wind that can cause the board to oscillate up and down and will surely cause damage. No way would I use that system - especially for a couple of boards stacked up - for a 5 to 10hr drive. How do you get the right hold on a SUP and surfboard at same time? Or two windsurf boards say slalom and wave? Can it
I stick with the old standard straps, they are way cheaper, infinitely adjustable, don't slip, and for safety I use two on the front if travelling any distance. Plenty of times I have done 110kph into a 30kn wind = 150kph so I'll run with cheap and works.
Only advantage I can see with Lockrack is simple for dummies and theft proof. Anyone with a lot of gear and going to the beach a lot buys a van or wagon = simple and theft mitigation too
