If you know they're going to use foam insulation, install 3/4"
contacts.  Strip back about 10-12" of the outer jacket from the cable
and coil up the inner conductors in the 3/4" hole beneath the contact.
There will be enough space in the hole to pull the wires out.  If any
foam comes in contact with the wires, use a long pair of tweezers or a
needle nose to gently work them loose.  Although acetone will melt foam
insulation, it can also damage the PVC insulation (it's used as a
solvent to melt PVC).

Side note: Although I haven't tried it, one fellow I know says he puts
a bit of cable pulling greases on the wire to keep the foam from
sticking.  The stuff doesn't hurt PVC so it probably works but I'd test
it before relying on it.
