Not that I'm aware of . . . and the threaded length
of the barrel is prohibitively short for adding
insulation.
Go to lumber yard and get a coupon of Formica.
The kitchen remodeling department has racks
of 2 x 3 inch samples.
Drill clearance hole in your mounting surface
with .03 to .05 clearance all around the
jack's mounting hardware. Place a Formica
insulating sheet on the back side of the
mounting surface to support the jacks in
isolated splendor. You can bond the insulator
to the back side of the panel with E6000
so that there are no new fasteners coming
through to the front.
Had a few minutes this morning to drink some
coffee an peruse the 'net. The rest
of the family isn't up yet . . .
Bob . . .
