Tried to figure out appropriate tags for certain type of bondage and failed. (for the most part)

Middle character in post #1417168
has sleeves(?) on arms and legs with straps attached to bolts(?) on the floor.

(Being bound to the floor seems like it should have its own tag)

Not sure what to call those things in the floor, look like a cross between an u-bolt and an eye-bolt. I'm sure there's a term for them (I think some sailboats may have them to put rope through).

EDIT: Hmmmm, *checks Wikipedia* ... ahhh
https://en.wikipedia.org/wiki/D-ring !! (D-ring seems the closest so far)

Added tags arms_tied and legs tied, not sure what other tags would be appropriate.

(apologies for posting bondage tag question here. I tried to find general bondage-tags thread, but failed to find one)
