Product Details

Universal Coupler Lock (580403) by Bulldog®. Finish: Chrome. Limited Lifetime Warranty. Don't let your trailer walk away. Secure your ball mount to the vehicle with a locking hitch pin, and then lock the coupler so the trailer either can't be hitched or unhitched without the key. This top-grade product is expertly made in compliance with stringent industry standards to offer a fusion of a well-balanced design and high level of craftsmanship. Manufactured from industry-leading materials using up-to-date equipment, it ensures everlasting reliability and enduring value. This product is distinguished by total quality assurance, unsurpassed by anybody else.

It takes a key to start up your tow vehicle and drive it away. But anyone with a tow vehicle of their own can uncouple your trailer, couple it to their truck, and drive it away. So a simple lock through the coupler can keep it from being uncoupled. And an unattended trailer can meet the same fate. The same lock can keep your coupler closed, keeping someone else's trailer ball from mating, preventing theft. But thieves are canny; they know that even if the coupler is locked onto your hitch ball, it's easy to pull the pin on the ball mount, mate the mount with their receiver while it's still locked, and steal your boat, RV, race car or whatever.

Even if the trailer is locked away behind a fence, if you leave the ball mount in place while not towing, it's a matter of ten seconds to pull the pin and boost the mount. Especially if the mount is expensive, like an elaborate weight-distributing system. You'll need a small lock for the coupler, and a locking pin for the ball mount. Be aware that 1-1/4" receivers use 1/2" diameter pin, and 2" and larger receivers use a 5/8" pin.

Best Hitches Made

Bulldog® 028287 - Low Profile Latch A-Frame Mount Coupler for 2" Balls (7000 lbs)

This hitch replaced an old one I had to put a bolt through to keep it secure. It had come loose once but I was lucky the safety chains kept it with the truck but the big dent still remains in the fender. Bulldog hitches are simple and I no longer worry about whether the trailer is securely attached to my vehicle. I just cut the old welds, ground everything, smooth, welded the Bulldog in place, added some spray primer, (the whole trailer will get paint when it warms up), and I am ready to roll. Both my trailers have been modified with Bulldog hitches.

Adjustable Coupler Channel

Bulldog® AC300 0300 - Trailer Coupler Adjustable Accessory with 8" Height, 4 Hole, 3 Position Channel

The adjustable channel & coupler is a great addition to my trailer? it will help when connecting to different high tow vehicles, I already have a few different drop draw bars but this will make it even easier to set up the high properly. Excellent product, heavy duty.
