Searching for Anlin Malibu frame latch

I've seen this keeper in the past, but it's unfortunately not something we sell. The only products we have are the single hole variant of your double hole style. See our 89-029 and 89-041 for two examples.

These single hole variants may very well work for you, if you have enough room to stack them. Review their dimensions and see what you think.
