Video Transcript for R Products Flat T-style Hook and Keeper Door Holder Review and Installation

Hi, everyone, Adam with Today we're gonna be taking a look at some Jr Products hook and keeper. These are gonna be for your RV or enclosed trailer doors. Not a lot of these trailers come with these kind of props for your doors from the factory, this one didn't. And that's why we're putting one on today. But this is just gonna be ideal for either at the job site or even if you're moving someone in, loading and unloading, or if you're just at you RV and you're tired of having your door swing open. This is just gonna allow us to be able to set the right amount of length between our two brackets here.

Just to get that ideal spot, to keep this open. Just so we don't have to have it closing on us all the time. I know with this trailer specifically, it's really dark in there, so the more sun we can get in there, the better. And with this door open, even if we're unloading off the back, it's definitely gonna get that done for us. So this kit also comes with a rubber stopper for our door.

So when it does end up hitting the rubber stopper, we don't have to worry about it running directly into the enclosed trailer itself. It's also gonna help our hinge from overextending. Which is just gonna add to the longevity of your door and just make it all a lot quieter. Especially if the wind does take it out and, whack, into it. Luckily we'll have that there.

So this one in particular is flat. So it is gonna be probably one of the more low profile hooks that we have here, especially from Jr products. So if that's something you're looking for, go for it. If not, Jr products does have some others that are a little bit longer, some made of zinc. And all the other ones are gonna be rounded here.

You're gonna stick out a little bit more, but to be honest it's not really much of a difference. So yes, this is a little bit more intense than maybe just taking a rope, tying it through here, and tying it off somewhere else. But to be honest, it is a lot more professional and it really isn't that difficult to install. So let's just go ahead and show you guys how easy it is. So when mounting our first bracket obviously we need to find the right place to do it, but we do have included hardware. They don't really work for application cuz we wanna go all the way through the door and then put bolts on the back end of it. So you might have to make a trip to your local hardware store to grab the appropriate gear. I'm just gonna use a longer little bolt here and that should do the trick. I'm just gonna find a little spot here. And as I open up this door, I wanna make sure that we are gonna have a good spot to put the other section. So it will line up properly. So as I shut this door about here. And one thing we just need to make sure is we're gonna have it in the right orientation as well. So it can make that contact. So as we kind of come in like this, my idea is just to kind of, as I'm opening that door, it's gonna slide in there and obviously then it's gonna be able to support it. So it is gonna work, but I know I can get through this door but I just wanna make sure on the inside of the trailer itself, we're gonna be able to get to the back of our bolts. So this is where the bolts are gonna come through. So we're good there. So now we go ahead mark our marks and we can start drilling this bracket to get this one installed first. I always just like to use a paint marker. Just like this. And we don't need a whole lot, I just need enough just to know where I'm gonna be going. So now we just want to go ahead and pick our right drill bit. I'm using a 3/16th inch drill bit but we could go bigger or we could go smaller. It just depends on what kind of hardware you guys are planning on using. So just grab that and then you can go ahead and start drilling away. Perfect. And then now we're hitting the wood, so I wanna go a little bit faster. Awesome. And we'll do the same exact thing for the other four holes we marked. So making any holes in our trailer here, what we wanna do is use some Butyl Tape so that we can get all of that water from getting into those holes we drilled. This is just going to prevent any of that water getting down in there, rotting stuff out, and just causing unnecessary damage. So this is what it'll kind of look like. You guys can do your own little twists and things if you want. But, all we just wanna make sure of is that it's gonna cover the hole and we have a washer on the other end of our hardware here. Cause we will have to supply them for these brackets we're putting on. So with that into place, we can go ahead and try to get that lined up in the hole, just like that. I wanna get it all the way through. And we'll do that same exact thing for all of our other bolts. So we did have to source our own hardware for this, like we said earlier, but what you guys need to remember when picking these is first, we just need to make it small enough to go through the bracket. And second, I do suggest going all the way through and then putting a nut on the inside. If you're just self tapping on the outside of these enclosed trailers, eventually you're gonna see some flex in that outer paneling. This is just going to be the better overall way to do it with our enclosed trailer here. So now we're gonna go ahead and put our nuts on one side like this. We're gonna do that for all of them. And then we'll go around front and tighten them all down. So by going all the way through and putting a bolt on the back end, we don't have any flex. This bracket is completely solid. If we just use self tappers, which I recommend not doing, we would see a bunch of different flex of this outer shell here, but with this it's good. And if you guys get a little bit closer, you guys can see how that tape is making that seal really nice. You can either maybe cut off all the excess or just kind of work it with your hands to kind of just get it into that groove a little bit more. But we won't have any issues with any water getting into these holes. And that is exactly what we we're looking for. So we're gonna go ahead and repeat the same exact process with our second bracket that we did on our first bracket on our door here. You guys know the drill, put some tape over top of it. We're going to get our bolt, push it through, get a washer. We're gonna go ahead. Just put some nuts on the back and then just tighten 'em up just like before. So this kit does come with a rubber bumper for your door. We actually already had one installed but it is not near as long. So with this new bracket I think it's gonna be best for our fit just to put a longer one on there. As you can see we're gonna at least double the amount of bumpage. So what we're gonna do is we do have a bolt that comes with our kit and what we're gonna do is pretty much just take it and we're gonna put it in the smaller end, just like that. And we will have to take a screwdriver push it through just like that. Then we can go ahead and just screw it into place. All right. Once it's good. Make sure it's good. Then we're pretty much done there. Well everyone, that just about does it for our look at the Jr Products hook and keeper for your RV or enclosed trailer doors..

Just what the doctor ordered LOL this is a great upgrade to my RV The old one was plastic and broke, it had no chance to last! This product fit perfectly did not have to drill any new holes to mount this door latch. So very happy. THANK YOU


Just what I needed.


worked great


Just received and installed the latch. Looks like it will out last the original polycarbonate original. Only time will tell..


just what I was looking for


The product is exactly as advertised! Higher quality than the cheap plastic part used by manufacturers and most replacement parts available locally. Love the stainless parts and the appearance is way nicer than the black plastic.


I received the package and the parts are in great shape.; They are made in taiwan and of good quality. They feel solid, but I will see how they hold up over time. My old plastic ones were not as good, I think these will last much longer!


Eazy to Install and will not Rust! Great Value


Exactly what I needed to replace my old one. I’ve already replaced them several times with the stock plastic ones but this one likes it should last a while.
