Looking for the best quality , LOCKING , flush mount, 2 3/8-2 1/2 " , cam style latches available for my deck storage doors. I have the non locking ( not sure of manufacture) type on my aluminum boat now. They function ok , but do leak some water . I'm confident it's coming in around rod that attaches to latch . Is this common , even with new cam latches? If not is there a brand out there that is more waterproof , that locks ? Thanks in advance !!!
