B & W Defender Locking Gooseneck Coupler

The Defender coupler, made by B & W, is also called the "Defender Locking Gooseneck Coupler."

A gooseneck coupler is the piece that is inserted into the neck of a gooseneck trailer, then coupled, or hitched, onto the ball in the bed of the truck.

About The Defender Coupler

The Defender coupler is highly popular for several reasons, including:

• Cone Shaped - The bottom of the coupler, the part that goes over the ball and hitches onto it, is cone shaped. This helps to funnel the ball into the hitch, making hooking onto the trailer easier.
• Automatic Latch - When you lower the trailer onto the ball the Defender coupler automatically latches. With other types of couplers you have to manually latch the coupler to the ball, often requiring you to lean awkwardly over the side of the truck, or to crawl into the bed.
• Integrated Lock - The Defender hitch coupler has an easy-to-use push button lock. You can lock your trailer when coupled (to prevent unauthorized un-hooking of the trailer) or uncoupled (to prevent unauthorized hooking up to the trailer).

The B & W Defender gooseneck coupler is made in the USA in Humboldt, Kansas.
