Larson sundeck latch

[brandon456]

I am new to the boat world and bought my first boat. 1999 larson 206 lxi. The transom cover sundeck does not have any way to latch. When trailering it blows open if I don't use a ratchet strap to keep it down. How is this supposed to be latched? Does anyone have a picture of the way this should work? I'm guessing someone replaced the original sundeck
thanks!
