looks neat , do they release by presure ?

: Well after putting this method of building hatches through multiple
: tests, they have proven very well. I have been on multiple
: camping trips, put them through some nice breaking waves, and
: have done a lot of rolling and still no water. My Objective was
: to build something that is flush, small flanged, light, strong,
: inexpensive, and most important watertight! The latch is made of
: abs and stainless steel components. The flange is actually
: backward than most ways of building hatches which makes it work
: so great. I do have a temporary piece of foam on them now but it
: has held up great so I just might not change it. I had a lot of
: intrest in them at the RedFish 13th Annual West Coast Wooden
: Kayak Rendezvous so I figured that I would post them here as
: well.
