Video Transcript for Review of Trimax Locks Trailer Tongue Lock - Surround Lock - TMX85QR

Hello, everybody. This is Jeff at etrailer. Today we're gonna take a look at this Trimax Universal Trailer Coupler Lock for the one and sevens eights inch, two inch, and two in five 16ths inch couplers. Now this is a dual purpose design, so it combines a coupler lock and an integrated U lock. It is a universal fit for multiple coupler types. It will fit your standard latch style couplers that have the latch on top.

But what's nice about this lock, it will also work on the newer low profile Bulldog and surge brake couplers. Just to show you what we're talking about, I'm gonna pop up an insert and show you, there's an example of a surge brake coupler that has the lock already installed on it. The U lock design we mentioned has, when you remove the ball, the ball can be removed, and then you can use it as a wheel lock on smaller size wheels, or using it with chains in cables. And just to show you how this would work, in other words, you have your plug right here, this red plug. Just hold this and unplug it.

Then you get two keys. Just line the key up with the slot in there. And once you get it lined up, just turn your key 180 degrees and it stays in there. And then you can pull your big, large U bolt right out. It is a seven eights inch hardened steel hex shackle construction.

And then, as we mentioned, if you wanted to you can remove the ball. And then just use it as a U lock like that, as we mentioned on maybe either a small size wheel or change your cables. But if you're gonna use it on a coupler, install that back in there. And then what you can do is rotate this closed. And then it has a ratchet style lock in here.

So you'll notice when you put your large U bolt back in there and you push down on it, you just push it as far as you can till it's tight, and then it's all locked, ready to go. You don't have to lock it, unlock it, and all that. And then it's locked, just like that. And then to unlock it again, just take your key, line it up, turn it all the way, and then slide it right out. Very simple to use. It is a solid die cast body construction. Has a nice dual lock system for maximum cut resistance. And again, just put it in there, push it down to where you need it, and you're all ready to go. Simple as that. Put your plug back in there to protect the lock there. But that's gonna do it for a look at this Trimax Universal Trailer Coupler Lock for one and seven eights inch, two inch, and two in five 16ths size couplers.

Man this trailer lock is a beast! 7/8” steel and it also alows for the chains to go underneath. If anybody cuts this, they will have to cut it in 2 places. No would be thief is going to waste their time on this bad boy. And if they do Im sure the noise would wake the dead as this shaft is solid steel.
I feel that my enclosed trailer is Safe Safe Safe!!!
My previous church has had 2 trailers stolen and I recommended this to him so there wont be a #3.

  • Will etrailer Lock Set Work With Curt QuickPin No Latch A-Frame Coupler
    Hi David! The surround coupler lock included with the etrailer Trailer Coupler Lock Set # e22GV will fit your Curt QuickPin Coupler # C84DR. However, the other locks won't be able to fit with the surround lock in place if you're wanting to replace the QuickPin as well. It looks like you ended up ordering the Trimax Coupler Lock # TMX85QR along with the Curt Hitch Lock # C23025. Those will work together to keep your coupler secure. The # C23025 is recommended by Curt for the # C84DR and...
