Bulldog BX1, A New Generation in Gooseneck Couplers

Bulldog BX1

The Bulldog BX1 gooseneck coupler is the result of generations of design expertise and field experience.   The new ball pocket design provides contact on both sides of the ball for substantially improved pull out strength and features the only sliding-plate design that transfers part of the load to the top locking plate rather than only the bottom locking plate.

Traditional locking plate styles only contact the ball on one side, where the new BX1 coupler contacts the ball on 2 sides.

The Bulldog BX1 bottom locking plate is 50% larger than other competitors, letting you miss by more than an inch while still allowing the ball to guide into the socket easily.  The contour-formed edge on bottom locking plate fits the ball better and reduces jarring and the ever- increasing cam tightening locking mechanism provides a continuous tight ball fit.

The new Bulldog BX1 locking handle design operates easily with one hand making hooking up and disconnecting quick and easy.

The Bulldog BX1 coupler also features a theft resistant design which allows pad locking the coupler to the ball (lock not included).

If you’re looking for a gooseneck coupler that delivers unmatched strength through its heavy-duty construction, easy vertical height adjustment  and flexible mounting options with the Next Generation locking plate coupler locking mechanism, the Bulldog BX1 is your choice.   Backed by a 5 year limited warranty, the Bulldog BX1 will give you years of trouble free service.
