Thule Stacker straps

So this might be a random question, but I couldn’t find the answer anywhere on the internet, so thought I’d post it here. I recently bought a Thule Stacker kayak rack, and we have 2 kayaks to transport… I bought the extra front and back racheting tie downs, but we only have the 1 set of regular tie down straps. Does anyone out there have a Stacker, and do I need to buy another set of straps, or will one set work alright to go over both of them? Thanks in advance!

that depends
Are you putting both kayaks on one side of the Stacker, or a kayak on each side?

If you are going both on one side then one strap for the front Stacker, and one for the back.

If you are going with a kayak on each side then you will want a 2 straps for the front and 2 for the back. One strap is for the kayak one side and the other is for the opposite side.
