(Honest question.) Should the beam handle an additional 1000 or 5000 lbs,
in view of your first paragraph?

FYI...
Accepted safety margin for any product used for overhead
lifting or rigging is 5X. In other words, if your intended
maximum load is 1,000 lbs., all hardware being used should
be rated to no less than 5,000 lbs.
I trust you've already confirmed the I beam (and its
supporting structure) will handle an additional 1,000 lb.
load at the intended lift point.

The truth as I perceive it to be.
Your perception may be different.

I-beam is 5-1/4" wide, no rollers needed, and a clamp good for 1 ton
will be at least twice as strong as anything I'll be needing to lift.
The i-beam is actually up in a joist (runs parallel to them, of
course), and one problem I might have is there's only about 1-5/8"
clearance between the side of the i-beam and one of the joists. The
joist on the other side of the i-beam has at least 6" to 8" clearance,
so that side should have plenty of room to get a clamp in. I'm just a
little worried about the narrow clearance side. TIA.

Try a commercial plumbing supply store. Quite often larger piping (ie 3-12")
is hung from the beams in buildings. The hangers are attached to the beams
with clamps. Another source may be a tool rental outlet.
