Video Transcript for Trimax Dual Purpose U-Lock Coupler Lock Review

Right here is the Trimax lock for your trailer couplers. This is gonna utilize this top piece here and the bottom piece and the way it works, you just put it in your trailer coupler. You're gonna lock it down onto it just like that, and then we're gonna put this down, loosen it up, and then lock it into place, close the door, and then we are good to go for storage for however long. There's really only one thing that's gonna prevent it from not working, and that's just the width from the little housing right here. So it's about 4 3/4 of an inch. So I would say just measure the lip of your coupler, and if it's in between zero and about 4 3/4 of an inch, I think it's gonna work.

It's gonna work with all your coupler sizes. If you have a coupler for a inch and 7/8-inch ball or if you have a two inch like we have or even the bigger ones, like a 2 5/16 inch, it is gonna work. The way it really works is we have a key here. It's gonna be pretty much pick-proof since it's the circular key, we get two of them. So maybe store one somewhere safe and then keep one on your keys.

So basically, we just gotta put this in here line it up, loosen it, and then once it's loosened, you can see on our steel little U-bolt right here, we're gonna have a bunch of different notches. So if it is a taller coupler, it doesn't have to be one like this. It still is gonna work. So it does give you a lot of adjustments so you can really get it nice and secured up to your coupler, just like that. So you don't have to worry if it's not gonna fit or not.

Our shackle is gonna be made of hardened steel and it does have a diameter of 9/16 inches and it is going to have the housing made of a very durable nylon. So this is gonna help absorb some of those shocks if someone's trying to beat this with a hammer or a pry bar. This is so tight. I really don't see this thing really coming off. Something I would add to this is something to lock this part from disconnecting from the ball.

The lock's still gonna stay on there, but that's just gonna be one extra thing. So let's just say for some reason, they get it to where the lock is undone. If this is still locked, that's another thing they have to do. So like right now, it's unlocked, but the coupler is still holding onto the ball. So if we had that locked into place, that would just be one more step that that theft person had to do to get this undone. This is just gonna provide added security throughout the whole entire year, especially if you're just storing it, and especially if it's with a bunch of different boats, you wanna be the one that has a visible lock on it just because that's the one they're probably not gonna pick. It also just gives me peace of mind knowing that my boat's gonna be there for the next season..

    I have a solution that is keyed alike and will save you some money but the Trimax Dual Purpose Coupler Lock and U-Lock with Ballistic Grade Nylon Housing - 9/16" Shackle item # TMX47FR isn't able to be keyed alike.

  • Trailer Coupler Storage Lock Keyed Alike For 1-7/8", 2", and 2-5/16" Couplers
