Curt Hitch Covers - Hitch Cap Sensor for 2-1/2 Hitches - C36UR Review

Hi there, I'm Michael with Today we're gonna take a quick look at this Curt, two and a half inch hitch cap sensor. This is going to attach to the two and a half inch by two and a half inch trailer hitch receiver on your 2019 newer GMC Sierra and your 2021 newer Chevrolet Silverado trucks. This is not going to obstruct your trailer hitch or towing accessories, it's got two pieces there that will allow it to clamp down on the top and bottom so that it will work on the outside still allow you to easily put your phone out and that sort of thing inside there without having to worry about it whatsoever. This sensor is going to work in sync with your trucks electronics to prevent the inner tailgate on your GMC MultiPro or Chevrolet Multi Flex tailgate from folding down when you have a ball mount or other accessory installed in your hitch. Now, it's possible that it will still alert you if the cap is raised like this, and maybe you just forgot to close it.

So you will wanna make sure that you're always closing the cap when you don't have an accessory in there so that the sensor will allow your tailgate to fall down. This is very convenient way of just kinda giving you a second set of eyes to make sure that you're not gonna have anything that could damage your tailgate before you lower it in place. And because it is very easy to get installed with the included wiring harness, it's just gonna plug right into your tail light wiring. They do include instructions here. So because of that, it's going to be a very simple way of just kinda giving you an extra check to make sure that you're not gonna damage your tailgate.

This is a nice black plastic construction, So it's going to be a nice sleek design suited for all work conditions, whether you're just doing some recreational towing or if you're hauling for a job. As far as our dimensions go, this is right at four and seven eighths to just shy of five inches tall by about five and a quarter of an inch wide and about one and a half inches deep. This will include both the sensor cap, the wiring harness, and then a few zip ties for you to help route your wiring up to where it's gonna plug in. That's another really nice thing about this installation is that these are all plugged options so you're not gonna have to worry about splicing into your vehicles wiring to get it connected, it's all just gonna be very easy to get plugged in, just like the instructions show they do have pictures to walk you through step by step. So again, very easy to get this installed.

And it will just provide that extra check to make sure that your tailgate isn't gonna drop down when you have a bomb out there that could damage it. So that's gonna complete our look for today. Again, I'm Michael with I hope this video has been helpful for you in deciding if this is going to be the right fit for you, if not, we do have lots of other options here at, so I hope you check them out. Thanks for watching.

We'll see you next time..
