Once installed it stays on, making it convenient to on, making it convenient to use anytime -- no more fumbling around with removable locking devices! Perfect for use in tractor-trailer applications as well as RV, buses and more. Made in the USA. 

How it works:

  • Remove the yellow knob and install the Watchdawg using one of the included adapters. 
    Pull the knob out to apply the brakes.
  • Insert key and unlock, enabling the Watchdawg to slide back and forth.
  • Reposition the Watchdawg against the dash and turn the key to lock. Locking the knob against the dash prevents brake release.
  • Return the knob to operating mode by using the key to unlock, pull the knob to its outer position and re-lock. The brake valve will now operate normally. 

    NOTE: Red trailer knob is not included.
