“I’ve been in the hitch industry for 40 years & I’ve probably seen it all.  That’s why I invented JAW LOCK – because my customers needed something to protect their holiday time and investment.”

“Try JAW LOCK – it really works!”

– Jim C.

Enjoy Your Vacation!

The team at Sentry Five understand the value of peace of mind.  JAW LOCK  is a small device that saves big problems:

  • A hitch can be stolen in under 10 seconds, leaving your rig stranded
  • A single, unexpected hitch replacement can devastate your holiday budget

JAW LOCK takes these worries away by securing your hitch.


“Jim and his team are great to deal with – I’d rather be safe than sorry.”

“No one expects it will happen to them, but losing a hitch really killed our vacay.”

“I never even thought someone would try to steal a hitch!  I chose JAW LOCK.”
