Listed fitments include Great Dane trailers from 1998-2017. The Wheeler Fleet catalog also lists Honda HR-V 2016-2020, which appears to be an error. This gladhand is widely used as standard equipment on many OEM trailers and meets SAE J318 specifications.

It combines a standard gladhand connector with a built-in quick-release valve, allowing the trailer's spring brakes to release up to 50% faster than conventional methods. The bracket-mount design bolts directly to the trailer, and the 3/8" bottom port connects to the service air line. It is typically replaced when the gladhand body cracks, the rubber seal deteriorates, or the quick-release valve fails, causing air leaks or slow brake release.
