I'm trying to locate a source for a part I need. It's a very 
small version of a clamshell vent. I want to use it to finish 
and protect a cable that runs through my cabin roof. I need one
about 3/4" that will handle an antenna cable. I have them on my 
loran and vhf cables. The give a finished appearance, protect 
the cable, and insure that there are no leaks.
I have located a larger size in various catalogs (1 3/4"). I use 
this size to protect/run larger groups of wires. I am unable to 
find any small ones.  
Thanks for any help.
