"Unlike coiled tubing or wireline, where the wire or tubing is always the same diameter allowing for a single unmoving primary barrier (stuffing box or stripper), snubbing uses a pipe, which will have an enlarged collar at the connection between the joints."
-- This is not always true, if you run VAM tubing it is fully smooth bore. The baker Tech Facts book can be cited as a reference.
You can also strip on a hydril, or annular preventer, which does not require you to go ram to ram.
there is also a "spacesaver" unit, which can be used to snub pipe till its heavy then the pulling unit or workover rig takes over.
