New Enforcer Design. Conceived by our very own Steve Arnesen, this little jewel is worth its weight in gold. Tony liked the concept so much that he had injection molds made to produce this specific application part. Two per package, make sure you have one for your whole fleet! Heres how the Pull-N-Seal works: Drill a 3/16" hole in your radio box, thread the antenna wire through the Pull-N-Seal and exit the box. Push the small end through the box, then pull to seal. The antenna wire hole is now secure and water proof, no more silicone globs. Can be removed and used over and over again.
