Video Transcript for Review of Demco Gooseneck Trailer Locks - Gooseneck Coupler Lock 30K - DM88KV

Hi everybody. Andy here with etrailer.com. Let's take a look at this Demco Gooseneck Coupler Lock. Now this is designed to provide security for your gooseneck trailer, specifically protecting it from theft and unauthorized use. This lock is specifically designed for gooseneck trailers rated up to 30,000 pounds. This is going to be ideal for owners of heavy duty trailers, including those used for hauling large equipment, livestock, or other cargo.

This is also an ideal solution for users who need secure, reliable protection for their trailer investments. And this is gonna be very simple to use. You're going to attach the lock to your coupler, and then you're going to slide the bar for the latch through, and then you're going to lock it in place with a padlock, which would be sold separately. So if you don't already have a padlock, that's something you'd have to pick up separately. This will prevent thieves from coupling your trailer to their vehicle and driving away with it.

So it'll be very simple, very easy operation. This is gonna give you peace of mind in an effective way to protect your gooseneck trailer from theft. And this is gonna be durable. It's gonna be very easy to use, give you strong security. If you own a trailer with a gooseneck coupler and you want to ensure its safety, this is going to be a an excellent option to consider.

Well, that's gonna wrap up our real quick look today. I do hope that our brief time together was helpful for you. Again, my name is Andy, thank you for joining me.

  • Will The Demco Lock DM88KV Fit My PJ Trailer With a Demco EZ Latch Coupler
    Hey, Johnny! The Demco gooseneck coupler lock part # DM88KV will definitely work for your PJ gooseneck trailer. As long as it has the Demco EZ latch. The lock specifically designed for their EZ Latch gooseneck couplers that are rated for 30k. I believe all of their gooseneck couplers are rated for 30k like part # DM73KV so you should have no issues with fitment.

  • Recommended Coupler Lock For A Demco 30k EZ-Latch Gooseneck Coupler
    Hey Bob, Yes, for a Demco EZ-Latch gooseneck coupler you would want the Demco Gooseneck Coupler Lock # DM88KV. This lock will cover not only the hole for the gooseneck ball but the EZ-Latch as well so that no one can pop open the coupler and take off with your trailer. You would attach the lock to coupler and then slide the bar for the latch through and lock it in place with a padlock (sold separately).

  • What is the Diameter of the Lock Hole on the Demco Gooseneck Coupler Lock - 30K?
    Hello Shawn, That is a really great question. I always consider it a great question when I cannot find the information anywhere on the internet. I also enjoy a good excuse to stretch my legs, so I grabbed my tape measure and took a stroll out to the warehouse. The lock hole on the Demco Gooseneck Coupler Lock # DM88KV is exactly 9/16". I attached an image for reference. The Master Lock Laminated Steel Padlock # ML312KA would work great with this coupler. What kind of gooseneck trailer...
