The surge strips are (I hope) "relocatable power taps" (XBYS). "This listing covers relocatable power taps rated 250 v, ac or less, 20 amp or less, which are intended for indoor use as relocatable multiple outlet extensions of a branch circuit to supply laboratory equipment, a home workshop, home movie lighting control, musical instrumentation, etc."
The "Etc" covers a lot of ground.
