Looking to mount a waterproof pelican box up inside the kayak, between the knees. I want to glue in a mount of some kind that comes apart into two pieces that slide together for a really secure “click” that won’t come undone without the push of a button or something.
So glue one side to the “ceiling” of the deck and and the other to the box.
No, not like that. More like two thin plates, about 3x4” or so that slide into each other and click lock.
Something what comes with some wearable flashlights or a quick mount for a bike handlebar or something.
Can’t help with the click mount idea but my first thought reading the OP was safety. A box located like that would slow down a wet exit, maybe even trap your legs.
