I think laxative is what you mean.  It will take care of strain 
relief! Jim WA6EKS

Dave and ED,

Tnx for replies.    Both you guys got me going in the right 
direction.
  Looks like "strain relief bushing" is  a good name for them.   
It
kicks up a bunch on ebay  and tomorrow I'll sort through and make 
sure I
get the right size.

Tnx again, Steve KW3A

 I'm tinkering around with a little project that will have 2  
cables
 (like microphone cable size) entering a metal box.    I can use 
rubber
 grommets to protect the cables, but  they could accidentally 
pull
 through the grommet.

 I could use zip ties, or hot glue, or knot the cable inside the 
box to
 prevent a pull through, but that's kind of rinkey dink.

 I've seen hard plastic things that fit the chassis hole and when 
the
 cable is passed through, a little thing on the inside clamps 
down to
 lock the cable.   Anybody know what these things are called?   
I'd like
 to look on ebay, but have no idea what item to search for.

 Tnx, Steve KW3A
