Try the thick black foam that is used to insulate 3/4" or 1" copper pipes. The stuff I get is usually ~ 1 1/4" to 1 1/2" thick, so the OD of the insulation is about 3 1/2" to 4". I cut it to the length / height I want and viola, instant cable elevators.
Not nearly as nice as the ESD Cable Elevators (which I also have) but for a few dollars - they can't be beat!
