SeaDog Line 354-2271411 Lock for Doors, Adults, Unisex, White, One Size

This style catch was on my 2001 Seapro. the original lasted nine years, and I went a while with an annoying rattle because West Marine was indifferent to finding the vendor. I finally found these online. They fit fine, but they are not as sturdy looking (the bases, rollers and arms are thinner). However, the package has four sets, so I should be ok for as long as I want to keep the boat.

I used this door catch as a replacement for a broken one in my Bayliner. It was a direct bolt-on.
