It's called a "bar clamp" or sometimes, a "woodworker's gluing clamp".
The latter says it all. There are two types: a) just the two pieces for
the ends, through which one can put a 1/2" or 3/4" pipe as long as
desired; b) set-length with a relatively flat bar of metal between the two
ends. IMS, the included-bar type only goes to 42" Don't know if this is
sufficient for a B windscreen.
