The Pull-N-Seal concept is another Enforcer innovation and this tiny product is worth it's weight in gold. There is nothing worse than filling a hole in your radio box, well maybe having to drill one in the first place.... But it is a necessary evil after all. We developed this product to be able to seal one of the toughest tiny holes, the antenna wire exit. With the Pull-N-Seal you simply dill a 5/32" hole in the radio box, insert the antenna wire through the P&S, then push the assembly into the hole, pull and seal, that's it! You get (2) per package.
