BULLDOG has introduced the Rigid Mount Collar-Lok Coupler, featuring an anti-rattle design to help eliminate movement while towing, and downward bias levels under load to improve articulation from the trailer to the tow vehicle.

According to a press release, the collar-lok coupler’s force transfer feature resists damage and extends service life.

The coupler is designed for one-tool installation using four bolts, and includes a hexagonal depression to prevent nut rotation during assembly.

The coupler is available in a 7,000-pound weight capacity with a 2-inch ball (P/N 028584) and a 12,500-pound weight capacity with 2-5/15 in. ball (P/N 028585), both couplers carry a limited five-year warranty.

“We know our customers have experienced movement and rattling – it is a common phenomenon with adjustable couplers,” said Todd Walstrom, vice president/general manager of trailer/industrial products for parent Horizon Global Corp. “To address this situation, we’ve created the first anti-rattle coupler in the industry. Now, users can focus on the road, rather than the distraction of the rattler of their trailer connection.”
