Brake Tech Tools Fifth Wheel King Pin Gauge

Made in the USA: Crafted from premium stainless steel and meticulously cut and engraved. This brake gauge measures trailer king pin wear, height, and squareness with precision. Measure trailer king pin wear: slide the round opening in the gauge over the king pin to the "neck" area. If the gauge fits around the "neck" at the minimum neck area, the king pin is worn beyond serviceable limits according to the SEA J700 standard. Measure trailer king pin height and squareness: place the gauge 90 degrees to the bolster plate. If the gauge will not fit into the king pin recesses, the height of the king pin is incorrect or the king pin or bolster plate is bent. Multifunctional Brake Pad Measurement Tool: Effortlessly assess the condition of your trailer's king pin and bolster plate by rotating the gauge 360 degrees around the king pin. This brake tools ensure straightness and accuracy for optimal performance and safety on the road. Customer First: For inquiries regarding product innovation and usage, reach out to us anytime.
