This is for locking out air brake park valves and is not designed to stop someone but to be a deterrent. When working on the vehicle or a camper parked.
 
****New options.  The original V1 was for a school bus and does not work with all brakes. I made option V2 {red}  that fits more semis and if you look at the picture they have more of a gap between the yellow brake knob and the dash.
 

CLIMATE NOTE: This is printed in PLA plastic which is known to warp in higher temperatures or become brittle when exposed to UV light. If your car is in a hot climate and in the sun, the high temperatures (>125℉) and direct sunlight could warp this adapter or cause it to break. This particularly applies to places like Phoenix, Southern California, etc. where temperatures regularly reach into the 100℉. An average "hot" summer day in Minnesota, or Wisconsin, or New York could also warp these if your car sits in the sun! 
 
This product is 3D printed. Due to the nature of 3D printing, there may be a seam, layer lines, and/or small imperfections.
 
Washing instructions: Hand wash only with cool, soapy water. Rinse and dry.
