Yes. I made some from conduit that extended about 2" above the plugs.
I found it didn't mater whether or not the tops were covered with
metal, but I applied a bead of silicone RTV to prevent the sharp edges
from cutting through the wire insulation. I slit the bottom of each
tube lengthwise to make it easier to press it easier to press around
the hex part of the plug.
