Q&A's:
"does it have the swevil so it can be used with a swevil"
Matthew we are not sure what you are referring to here, could you be talking about a swivel for the back of the case to attach to your belt? If that's what you are asking then the answer is no.
"Does it have the ability to be worn on a belt?"
Hi Ron, yes this should have slots for a belt.
"Will a Kenwood TK-2180 fit in this product?"
The TK-2180 will fit in model 5471RC, 5480RC, or 5701RC Holsters.
