Aloha! I just placed an order for a Queens Keep. Here are my specs: Double oval base ring: 1 3/4 Gap: 3/8 Cage Diameter: 1 1/4 Cage Size: 1 1/2 Padlock, no security screw. I was planning to get the smaller 1 5/8 base ring but ended up not doing it. The 1 3/4 ring fits perfectly (I can slide two fingers under it, though I have small, narrow ass fingers). For days I tried putting on the 1 5/8 sizing ring but couldn’t make it work, so I take that as a sign that for at least the near future, I won’t be able to fit into one. Now comes the tough bit…the waiting!!!:-(
