The interesting thing to me is the post which will work in 20mm and 3/4" dog holes! Wish they sold the post in packs to be used with the Pannel Platform Kit. I have verified that they fit either version.

Hope to get some hands-on with them this weekend.
They have them at Lee Valley which currently has free shipping if you don't want to go the Woodcraft route.
