I have looked at these in your catalog..... thinking 26-357 for corner piece and 26-221 and 222 for internal.....only thing is the top latch is different as you can see . would 26-334 work better.. measurements seem to be the same on both

Thank you for posting. Our 26-221 looks a little closer, but it's hard to say for sure. The hole spacing is different than on the 26-334. You will have to get as exact a measurement as you can on your own latch to see which is best.
